StringView - Archive of obsolete content
the aims of this library are: to create a c-like interface for
strings (i.e., an array of character codes — an arraybufferview in javascript) based upon the javascript arraybuffer interface to create a highly extensible library that anyone can extend by adding methods to the object
stringview.prototype to create a collection of methods for such
string-like objects (since now:
stringviews) which work strictly on arrays of numbers rather than on creating new immutable javascript
strings to work with unicode encodings other than javascript's default utf-16 dom

Symbol - MDN Web Docs Glossary: Definitions of Web-related terms
in some programming languages, the symbol data type is referred to as an "atom." symbols don't "auto-convert" to
strings most values in javascript support implicit conversion to a
string.
... for example: let sym = symbol("sym") alert(sym) // typeerror: cannot convert a symbol value to a
string that’s a "language guard" against messing up, because
strings and symbols are fundamentally different, and should not occasionally convert one into another.

type the following lines into your browser's console: let lotsofdecimal = 1.766584958675746364; lotsofdecimal; let twodecimalplaces = lotsofdecimal.tofixed(2); twodecimalplaces; converting to number data types sometimes you might end up with a number that is stored as a
string type, which makes it difficult to perform calculations with it.
...there is a way to solve this problem — passing the
string value into the number() constructor to return a number version of the same value.

Building the WebLock UI
the url that the addsite method expects is a
string, so we can pass a
string directly in from the user interface, or we can do a check on the
string and verify that it's a valid url.
... in this tutorial, focusing as it is on the weblock functionality (rather than the ui), we'll assume the
strings we get from the ui itself are urls we actually want to write to the white list: function addthissite() { var tf = document.getelementbyid("dialog.input"); // weblock is global and declared above weblock.addsite(tf.value); } this javascript function can be called directly from the xul widget, where the input
string is retrieved as the value property of the textbox element.

string (which is not checked for validity) and passing it through to the addsite api we defined in the earlier part of the tutorial.

Making cross-thread calls using runnables

Mutable - MDN Web Docs Glossary: Definitions of Web-related terms
strings and numbers are immutable.
... lets understand this with an example: var immutable
string = "hello"; // in the above code, a new object with
string value is created.
... immutable
string = immutable
string + "world"; // we are now appending "world" to the existing value.
... on appending the "immutable
string" with a
string value, following events occur: existing value of "immutable
string" is retrieved "world" is appended to the existing value of "immutable
string" the resultant value is then allocated to a new block of memory "immutable
string" object now points to the newly created memory space previously created memory space is now available for garbage collection.
SQL Injection - MDN Web Docs Glossary: Definitions of Web-related terms
hackers use a simple
string called a magical
string, for example: username: admin password: anything 'or'1'='1 after clicking on the login button, the sql query will work as follows: "select count(*) from users where username=' admin ' and password=' anything 'or'1'='1 ' "; just take a closer look at the above query's password section.
...just due to a simple
string (magical
string) the entire database is compromised.
... how to prevent before executing the queries for the user credentials, make some changes like the following: $id = $_get['id'] (1) $id = stripslashes($id) (2) $id = mysql_real_escape_
string($id) so due to (1) each single quote (') in the input
string is replaced with double quotes ("), and due to (2) before every (') it adds (/).
... the revised magical
string fails to bypass the authentication, and your database stays secure.
Pseudo-classes and pseudo-elements - Learn web development
you could use these to insert a
string of text, such as in the live example below.
... inserting
strings of text from css isn't really something we do very often on the web however, as that text is inaccessible to some screen readers and might be hard for someone to find and edit in the future.
... a more valid use of these pseudo-elements is to insert an icon, for example the little arrow added in the example below, which is a visual indicator that we wouldn't want read out by a screenreader: these pseudo-elements are also frequently used to insert an empty
string, which can then be styled just like any element on the page.
... in this next example, we have added an empty
string using the ::before pseudo-element.

Functions — reusable blocks of code - Learn web development
every time we manipulated a text
string, for example: let mytext = 'i am a
string'; let new
string = mytext.replace('
string', 'sausage'); console.log(new
string); // the replace()
string function takes a source
string, // and a target
string and replaces the source
string, // with the target
string, and returns the newly formed
string or every time we manipulated an array: let myarray = ['i', 'love', 'chocolate', 'frogs']; let madeast...
...ring = myarray.join(' '); console.log(madea
string); // the join() function takes an array, joins // all the array items together into a single //
string, and returns this new
string or every time we generated a random number: let mynumber = math.random(); // the random() function generates a random number between // 0 and up to but not including 1, and returns that number ...we were using a function!
...when called, it always returns a random number between 0 and 1: let mynumber = math.random(); the browser's built-in
string replace() function however needs two parameters — the sub
string to find in the main
string, and the sub
string to replace that
string with: let mytext = 'i am a
string'; let new
string = mytext.replace('
string', 'sausage'); note: when you need to specify multiple parameters, they are separated by commas.
...as an example, the array join() function's parameter is optional: let myarray = ['i', 'love', 'chocolate', 'frogs']; let madea
string = myarray.join(' '); // returns 'i love chocolate frogs' let madea
string = myarray.join(); // returns 'i,love,chocolate,frogs' if no parameter is included to specify a joining/delimiting character, a comma is used by default.
Function return values - Learn web development
let's return to a familiar example (from a previous article in this series): let mytext = 'the weather is cold'; let new
string = mytext.replace('cold', 'warm'); console.log(new
string); // should print "the weather is warm" // the replace()
string function takes a
string, // replaces one sub
string with another, and returns // a new
string with the replacement made the replace() function is invoked on the mytext
string, and is passed two parameters: the sub
string to find ('cold').
... the
string to replace it with ('warm').
... when the function completes (finishes running), it returns a value, which is a new
string with the replacement made.
... in the code above, the result of this return value is saved in the variable new
string.
Making decisions in your code — conditionals - Learn web development
any value that is not false, undefined, null, 0, nan, or an empty
string ('') actually returns true when tested as a conditional statement, therefore you can simply use a variable name on its own to test whether it is true, or even that it exists (that is, it is not undefined.) so for example: let cheese = 'cheddar'; if (cheese) { console.log('yay!

Client-side storage - Learn web development
storing simple data — web storage the web storage api is very easy to use — you store simple name/value pairs of data (limited to
strings, numbers, etc.) and retrieve these values when needed.
... storing complex data — indexeddb the indexeddb api (sometimes abbreviated idb) is a complete database system available in the browser in which you can store complex related data, the types of which aren't limited to simple values like
strings or numbers.
...we do however need to pass the attribute through the global built-in number() object as it is of datatype
string, and therefore wouldn't be recognized by the database, which expects a number.
... storing complex data via indexeddb as we mentioned above, indexeddb can be used to store more than just simple text
strings.
Fetching data from the server - Learn web development
this can be done with replace(), tolowercase(), and simple
string concatenation.
...it also returns a promise (which resolves to the resulting text
string), so here we use another .then(), inside of which we define another function that dictates what we want to do with that text
string.
... we are just setting the textcontent property of our poem's <pre> element to equal the text
string, so this works out pretty simple.
... there is quite a lot of complex code that deals with filtering the products by category and search terms, manipulating
strings so the data displays correctly in the ui, etc.
What is JavaScript? - Learn web development
operations on pieces of text (known as "
strings" in programming).
... in the above example we take the

... // i am a comment a multi-line comment is written between the
strings /* and */, e.g.
...troubleshooting javascript storing the information you need — variables basic math in javascript — numbers and operators handling text —

string methods arrays assessment: silly story generator ...
JavaScript First Steps - Learn web development
after that, we discuss some key building blocks in detail, such as variables,
strings, numbers and arrays.
... handling text —
strings in javascript next we'll turn our attention to
strings — this is what pieces of text are called in programming.
... in this article we'll look at all the common things that you really ought to know about
strings when learning javascript, such as creating
strings, escaping quotes in
string, and joining them together.
... useful
string methods now we've looked at the very basics of
strings, let's move up a gear and start thinking about what useful operations we can do on
strings with built-in methods, such as finding the length of a text
string, joining and splitting
strings, substituting one character in a
string for another, and more.
JavaScript object basics - Learn web development
the syntax always follows this pattern: const objectname = { member1name: member1value, member2name: member2value, member3name: member3value }; the value of an object member can be pretty much anything — in our person object we've got a
string, a number, two arrays, and two functions.
...it is no wonder that objects are sometimes called associative arrays — they map
strings to values in the same way that arrays map numbers to values.
... so when you used
string methods like: my
string.split(','); you were using a method available on an instance of the
string class.
... every time you create a
string in your code, that
string is automatically created as an instance of
string, and therefore has several common methods and properties available on it.
Object prototypes - Learn web development
you will however also see some other members — to
string, valueof, etc — these are defined on person1's prototype object's prototype object, which is object.prototype.
... so object.prototype.to
string(), object.prototype.valueof(), etc., are available to any object types that inherit from object.prototype, including new object instances created from the person() constructor.
... you'll see other examples of prototype chain inheritance all over javascript — try looking for the methods and properties defined on the prototype of the
string, date, number, and array global objects, for example.
... these all have a number of members defined on their prototype, which is why for example when you create a
string, like this: let my
string = 'this is my
string.'; my
string immediately has a number of useful methods available on it, like split(), indexof(), replace(), etc.
Test your skills: Object basics - Learn web development
the required members are: name: a
string representing the band name.
... nationality: a
string representing the country the band comes from.
...each array item should be an object containing the following members: name: a
string representing the name of the album.
... once you've done this, you should then write a
string to the variable bandinfo, which will contain a small biography detailing their name, nationality, years active, and style, and the title and release date of their first album.
Adding a new todo form: Vue events, methods, and models - Learn web development
we can set the initial value of the label to an empty
string.
...so in our case, our event object will just be a
string.
...since name is already being trimmed by the .trim directive, we only need to test for the empty
string.
...but this is easy to fix — because we're using v-model to bind the data to the <input> in todoform, if we set the name parameter to equal an empty
string, the input will update as well.

contract contract @foobar/mycontract;1 {00000000-0000-0000-0000-000000000000} [flags] maps a contract id (a readable
string) to the classid for a specific implementation.
...the skinname is an opaque
string identifying an installed skin.
...the version
string must conform to the toolkit version format.
... note: versions of gecko before gecko 1.8.0.13 and gecko 1.8.1.5 contained a bug where if you use the comparisons <, > or =, the version
string had be two or more characters long.
Reviewer Checklist
make sure the patch doesn't create any unused code (e.g., remove
strings when removing a feature) all caught exceptions should be logged at the appropriate level, bearing in mind personally identifiable information, but also considering the expense of computing and recording log output.
...which one you choose depends on how the feature is implemented: a pure java service can't easily check gecko prefs, for example.]
strings there should be no
string changes in patches that will be uplifted (including
string removals).
... rev entity names for
string changes.
... when making ui changes, be aware of the fact that
strings will be different lengths in different locales.

Security best practices for Firefox front-end engineers
existing security controls sanitizing all
strings that enter the dom through apis such as innerhtml when running system-privileged chrome code, we sanitize all html fragments that are created for chrome-privileged documents.
... this policy includes all dom apis that take a
string and parse it into a dom tree.
...the linter makes an exception for code that uses
string literals that are hard coded in the source code, assuming benevolent developers.
... developers are able to avoid tripping the rule by using escaping functions in combination with template
strings, for example: bar.innerhtml = escapehtml`<a href='${url}'>about</a>`; in system-privileged chrome code, any kind of remaining scripts will still be removed by our sanitizer.
HTMLIFrameElement.findAll()

...because we don't want to keep typing
string signatures everywhere, we can end up with typos and hard to trace back errors, we use the sig object.
...for example, let's declare this with
strings: { name: 'maketext', sig: '(landroid/content/context;ii)landroid/widget/toast;' } we see there are no separating characters between the arguments.
...this is special: because a charsequence is an array of byte characters, we can pass simple javascript
strings to jni.jsm wherever a charsequence is needed.
L10n Checks
you pass both paths to the files, e.g.: check-l10n-completeness -i file en-us.dtd my.dtd the output the output of l10n checks shows the missing and obsolete
strings in a pseudo-diff format.
...oltip +fullzoomenlargecmd.commandkey3 +fullzoomreducecmd.commandkey2 +fullzoomresetcmd.commandkey2 +organizebookmarks.label -showallbookmarkscmd2.label migration/migration.dtd -importfromfile.accesskey -importfromfile.label +importfromhtmlfile.accesskey +importfromhtmlfile.label you can assume changed
strings when you see entities removed and added with a similar name.
...the output closes with a summary, giving the total counts of missing and obsolete
strings and some statistics on how many
strings are changed or not, excluding access and command keys.
...0 - quiet; 5 - show all messages merge in the source mode you can tell l10n checks to merge missing
strings and files into the locale files by setting a merge directory, e.g.: check-l10n-completeness -m output_dir suite/locales/l10n.ini ../l10n/ de note: only files which were merged will be saved in that directory.
L10n testing with xcode
xcode will import your translated
strings into the project by adding them to the project folder and replacing the existing
strings.
... navigate to the newly opened ios simulator window many

... now, you can navigate through the firefox app in the ios simulator, viewing both ui elements and accessibility
strings as you go.
Localization technical reviews
compare-locale we run the compare-locales tool on the new locale to get the statistics on translation of
strings and report basic errors.
...
string lengths in pipnss.properties there are some character limits in the security/manager/chrome/pipnss/pipnss.properties file that you should be aware of.
... it is best to look into each of these files to see if the localizer's
strings might be too long.
...to put it simply, when we receive your request, we expect that you have spent time testing your work and making sure all
strings have been localized and that your language pack is relatively functional.
Uplifting a localization from Central to Aurora
that indicates that the same
string has different translations on l10n-central and aurora, and you really want to make sure that your aurora clone doesn't have quality issues.
...say, en-us removed a
string for the release+2, and you fixed a typo in the
string that still exists in release+1.
... so you fixed the
string on aurora, and you removed the broken
string on central.
... that's gonna conflict, and you need to resolve that with your merge tool so that the resulting localized file doesn't have the
string any more.

Running Automated JavaScript Tests
another common use case is to run just one test, or all the tests in just one directory: jstests.py path_to_js_shell test_path_sub
string [ test_path_sub
string_2 ...
... ] this runs all the tests whose paths contain test_path_sub
string.
... thus, you can run one test by giving its filename, or any sub
string that is a sub
string of that test filename only.
... running jstest in a browser jstests also runs on browser, with the following command: ./mach jstestbrowser to run specific test, you can use --filter=pattern command-line argument, where pattern is a regexp pattern that is tested against file:///{path_to_obj_dir}/dist/test-stage/jsreftest/tests/jsreftest.html?test={relative_path_to_test_from_js/src/tests}
string: ./mach jstestbrowser --filter=pattern running jstests on treeherder when viewing treeherder after a push to the mozilla repositories, jstests run in the browser are shown as r(j) meaning "javascript reftests".
SavedFrame
to see the stack as the content compartment sees it, waive the xray wrapper with components.utils.waivexrays: const contentviewofstack = components.utils.waivexrays(somestack); accessor properties of the savedframe.prototype object source the source url for this stack frame, as a
string.
... asynccause if this stack frame is the asyncparent of other stack frames, then this is a
string representing the type of asynchronous call by which this frame invoked its children.
...if the asynchronous call was started in a descendant frame to which the requester of the property does not have access, this will be the generic
string "async".

An Overview of XPCOM
the application code used an interface from a library, stdio, to print the "hello world"
string out to the screen.
...of the three methods on the nsiid class, equals, parse, and to
string, equals is by far the most important, because it is used to compare two nsiids in this interface querying process.
... contract id a contract id is a human readable
string used to access a component.
...you can not have two methods with the same name that take different parameters, and the workaround - having multiple function names - isn't pretty: void foowithint(in int x); void foowith
string(in
string x); void foowithuri(in nsiuri x); however, these shortcomings pale in comparison to the functionality gained by using xpidl.

... a few examples: a hashtable that maps utf-8 origin names to a dom window - nsinterfacehashtable<nsc
stringhashkey, nsidomwindow> a hashtable that maps 32 bit integers to floats - nsdatahashtable<nsuint32hashkey, float> a hashtable that maps nsisupports pointers to reference counted cacheentrys - nsrefptrhashtable<nsisupportshashkey, cacheentry> a hashtable that maps jscontext pointers to a contextinfo struct - nsclasshashtable<nsptrhashkey<jscontext>, contextinfo> a hashset of

string [target_xpcom_abi] of the following format: {cpu_arch}-{target_compiler_abi} {cpu_arch} [platforms] represents the cpu architecture and may be either: x86 - i386 and higher series (including x86-64 cpus in 32-bit mode) ppc - powerpc series alpha - alpha series x86_64 - amd64/emt64 series in 64-bit mode (32-bit mode is still considered x86) sparc - sparc series ia64 - itanium series {...
...target_compiler_abi}[platforms] represents the compiler abi and may be either: msvc - microsoft visual c++ n32 - irix 6 c++ compiler gcc2 - gnu c++ compiler 2.x gcc3 - gnu c++ compiler 3.x or 4.x sunc - sun c++ compiler ibmc - ibm c++ compiler for example: firefox built with the gnu c++ compiler 4.0.0 for the intel pentium processor would have xpcom abi of x86-gcc3 the xpcom abi
string can be retrieved programmatically by using the nsixulruntime interface.
...o retrieve the abi of your firefox or thunderbird, open the error console (accessible through tools | error console) and evaluate the following javascript code: components.classes["@mozilla.org/xre/app-info;1"] .getservice(components.interfaces.nsixulruntime) .xpcomabi if either the cpu architecture or the c++ compiler are unknown, the application wouldn't have an xpcom abi
string and attempts to get it will result in error ns_error_not_available.
... if the application doesn't have an xpcom abi
string (due to the fact that either its cpu architecture or c++ compiler are unknown, as described in the abi naming section), you should use the operating system's name (without appending the xpcom abi) as the platform name in the install manifest etc.

stringforrow(hdr): return the
string value that the column will be sorted by getsortlongforrow(hdr): return the long value that the column will be sorted by is
string(): return true / false warning!
... do not get confused between getcelltext() and getsort
string/longforrow()!
... internally when sorting by your column a simple implementation objects in javascript are just "advanced" variables, so an implementation of the nsimsgcustomcolumnhandler interface looks like: var columnhandler = { getcelltext: function(row, col) { //get the message's header so that we can extract the reply to field var hdr = gdbview.getmsghdrat(row); return hdr.get
stringproperty("replyto"); }, getsort
stringforrow: function(hdr) {return hdr.get
stringproperty("replyto");}, is
string: function() {return true;}, getcellproperties: function(row, col, props){}, getrowproperties: function(row, props){}, getimagesrc: function(row, col) {return null;}, getsortlongforrow: function(hdr) {return 0;} } basically, all we are doi...
...ng here is making sure that both the text that is displayed to the user (getcelltext()) and the
string we sort according to (when the user decided to sort the view by our custom column) are identical.

HTML Drag and Drop API - Web APIs
a datatransferitem object represents a single drag item, each with a kind property (either
string or file) and a type property for the data item's mime type.
... a key difference between the datatransfer and datatransferitem interfaces is that the former uses the synchronous getdata() method to access a drag item's data, but the latter instead uses the asynchronous getas
string() method.

string(); this.message = message.to
string(); this.getname = function() { return this.name; }; this.getmessage = function() { return this.message; }; } because the previous code does not take advantage of the benefits of using closures in this particular instance, we could instead rewrite it to avoid using closure as follows: function myobject(name, message) { this.name = name.tos...
...tring(); this.message = message.to
string(); } myobject.prototype = { getname: function() { return this.name; }, getmessage: function() { return this.message; } }; however, redefining the prototype is not recommended.

string(); this.message = message.to
string(); } myobject.prototype.getname = function() { return this.name; }; myobject.prototype.getmessage = function() { return this.message; }; in the two previous examples, the inherited prototype can be shared by all objects and the method definitions need not occur at every object creation.

strings or dates containing illegal element values in iso formatted
strings usually return nan.
... however, depending on the implementation, non–conforming iso format
strings, may also throw rangeerror: invalid date, like the following cases in firefox: new date('foo-bar 2014'); new date('2014-25-23').toiso
string(); new date('foo-bar 2014').to

Introduction - Archive of obsolete content
you can identify the level of compatibility of web standards in gecko-based browsers looking at their user agent
string, which should include the gecko version.
...the user agent
string for firefox at the time of this writing (in us english, mac os x) is: mozilla/5.0 (macintosh; intel mac os x 10.9; rv:25.0.1) gecko/20100101 firefox/25.0.1 the highlighted section is the gecko version: 25.0.1.
... you can read and copy the user agent
string of any firefox window, choosing "help > troubleshooting information" from the main menu.
Supporting search suggestions in search plugins - Archive of obsolete content
your server should then decide upon the suggestions to offer using whatever means it sees fit, and return a json array of results: query
string the first element in the array is the original query
string.
... for example, if the search term is "fir", and you don't need to return descriptions or alternate query urls, you might return the following json: ["fir", ["firefox", "first choice", "mozilla firefox"]] note that in this example, only the query
string and completion array are specified, leaving out the optional elements.
... your completion list can include as many suggestions as you like, although it should be kept manageable, given that the display will be updating live while the user is typing their search
string.

string to nsiwebnavigation.loaduri (which can happen indirectly, e.g.
... by passing the
string to something that loads it in a <browser> or <iframe>), you must call checkloaduristr to be secure.

Rendering a list of Vue components - Learn web development
to make sure that vue can accurately compare the key attributes, they need to be
string or numeric values.
... make it required, and make its type a
string.
... the <script> contents in your todoitem component should now look something like this: export default { props: { label: {required: true, type:
string}, done: {default: false, type: boolean}, id: {required: true, type:
string} }, data() { return { isdone : this.done, } }, } now, over in your app.vue component, pass item.id as a prop to the todoitem component.
Accessibility/LiveRegionDevGuide
in at-spi, this is accomplished by appending ":add" or ":remove" to the event
string.
...in this case, the root event
string is object:text-changed with ":delete" and ":insert" being appended to complete the event type.
...the event.any_data field holds the entire text
string while event.detail1 is the start index while event.detail2 is the text
string length.
Embedding API for Accessibility
be aware that in debug builds, this can cause a great number of assertions (bug 71598) to use prefs in embedding, use something like the following code: #include "nsipref.h"; nsresult rv; nscomptr<nsipref> prefs(do_getservice(ns_pref_contractid, &rv)); prefs->setboolpref("bool.pref.name", pr_true /* or pr_false */); prefs->setintpref("int.pref.name", newvalue); prefs->setcharpref("
string.pref.name", newcharstarvalue); to manually add a pref to your settings, add a line like the following to your prefs.js: user_pref("accessibility.browsewithcaret", true); accessibility prefs reference the following is a description of what accessibility prefs give us (or will give us), for accessibility: functionality implementation works as of ...

Communicating with frame scripts
after the name, you can pass detailed data as a
string or a json-serializable object, and after that you can pass any objects it wants to pass to content as cpows.
... the message passed to the listener is an object containing the following properties: name
string containing the message name.
... after the message name, you can pass detailed data as a
string or a json-serializable object: // chrome script messagemanager.sendasyncmessage("my-addon@me.org:message-from-chrome", { details : "some more details" }); to receive a message from chrome, a frame script uses the global addmessagelistener() function.

Localization sign-off reviews
here is some of the criteria we use to perform sign-off reviews: increased amount of untranslated
strings we look for previously translated
strings changing to untranslated
strings in the new revision.
... newly translated
strings that shouldn't have been translated self-explanatory enough, right?
...to put it simply, when we receive your request, we expect that you have spent time testing your work and making sure all
strings have been localized and that your changes are relatively functional.
PR_LogPrint
syntax #include <prlog.h> void pr_logprint(const char *fmt, ...); parameters the function has this parameter: fmt the
string that is used as the formatting specification.
... returns nothing description this function unconditionally writes a message to the log using the specified format
string.

string.
... once you have a url interface in hand (nsiurl), you have a completely parsed representation of the original url
string, and you can query for the various parts of the url.
...there is a 1-to-1 relationship between uris and channels (if you go so far as to create a channel from a uri, which is not required if all you need is a parsed representation of a uri
string).

string(auri, aname, avalue, aflags, aexpiration); setpageannotationint32(auri, aname, avalue, aflags, aexpiration); setpageannotationint64(auri, aname, avalue, aflags, aexpiration); setpageannotationdouble(auri, aname, avalue, aflags, aexpiration); setpageannotationbinary(auri, aname, adata, adatalen, aflags, aexpiration); and likewise for items in the places database: setitemannotation
string(a...
...getservice(components.interfaces.nsiioservice); var uri = ioservice.newuri("http://www.mozilla.org/", null, null); annotationservice.setpageannotation(uri, "my_extension/some_annotation", "this is the annotation value", 0, 0); retrieving annotations there are corresponding getters for the setters above (see nsiannotationservice.idl for the exact declarations): from c++: getpageannotation
string(auri, aname); getpageannotationint32(auri, aname); getpageannotationint64(auri, aname); getpageannotationdouble(auri, aname); getpageannotationbinary(auri, aname, adata, adatalen, amimetype); getitemannotation
string(aitemid, aname); getitemannotationint32(aitemid, aname); getitemannotationint64(aitemid, aname); getitemannotationdouble(aitemid, aname); getitemannotationbinary(aitemid, ...
...ame, aflags, aexpiration, amimetype, atype) getitemannotationinfo(aitemid, aname, aflags, aexpiration, amimetype, atype) getpageannotationtype(auri, aname); getitemannotationtype(aitemid, aname); the returned type will be one of the value_type constants in mozistoragevaluearray.idl: after bug 377066 the value_type_* type handling was changed to this: type_int32 = 1 type_double = 2 type_
string = 3 type_binary = 4 type_int64 = 5 try { var value = annotationservice.getpageannotation(uri, "my_extension/some_annotation"); } catch(e) { // annotation does not exist } other functions getpageswithannotation(aname, resultcount, results); getitemswithannotation(aname, resultcount, results); retrieves a list of all pages/items with the given annotation.
Using the Places history service
nsinavhistoryservice.queriestoquery
string: returns a serialized version of the queries as a "place:" uri.
... you should not count on this format, always use this function instead of hard-coding your own query
strings.
... nsinavhistoryservice.query
stringtoqueries: converts a serialized query ("place:" uri) back to the actual query objects and options.
Using the Places keywords API
it has the following properties: keyword:
string representing the keyword url: either a url or spec represeting the url to associate to postdata: optional post data
string.
... fetching an entry by keyword the fetch() method acceps a keyword
string (or an object having a keywords property) and might resolve to a keyword entry with the following properties: keyword:
string representing the keyword url: the url represeted by the keyword postdata: optional post data
string.
... placesutils.keywords.fetch({ url: "http://www.example.com/" }, entry => { /* invoked for each found keyword entry */ }) .then(oneentry => { /* oneentry is either null, or one of the keyword entries */ }, e => { /* failure */}); removing a keyword the remove() method accepts a keyword
string.

Creating a Python XPCOM component
defining the interface make a file named "nsipysimple.idl" to define the interface: #include "nsisupports.idl" [scriptable, uuid(2b324e9d-a322-44a7-bd6e-0d8c83d94883)] interface nsipysimple : nsisupports { attribute
string yourname; void write( ); void change(in
string avalue); }; this is the same as the nsisimple interface used here.
...note: there are exceptions; see this discussion for information on the use of
string and w
string for unicode transfer.
... # _reg_clsid_ = "{a new clsid generated for this object}" # _reg_contractid_ = "the.object.name" def get_value( self ): # result:
string pass def set_value( self, param0 ): # result: void - none # in: param0:
string pass as you can see, the output is valid python code, with basic signatures and useful comments for each of the methods.
How to build an XPCOM component in JavaScript
implementation this example component will expose a single method, which returns the
string "hello world!".
...here's the xpidl definition for our helloworld component: helloworld.idl #include "nsisupports.idl" [scriptable, uuid(xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)] interface nsihelloworld : nsisupports {
string hello(); }; note that you must generate a new uuid for each xpcom component that you create.
...when set to true, and only if 'value' is not // specified, the concatenation of the
string "service," and the object's contractid // is passed as avalue parameter of addcategoryentry.
How to build a binary XPCOM component using Visual Studio
let’s specify a simple interface: #include "nsisupports.idl" [scriptable, uuid(263ed1ba-5cc1-11db-9673-00e08161165f)] interface ispecialthing : nsisupports { attribute a
string name; long add(in long a, in long b); }; remember to generate your own guid.
...they could look like this: h file: #ifndef __specialthing_impl_h__ #define __specialthing_impl_h__ #include "comp.h" #include "ns
stringapi.h" #define specialthing_contractid "@starkravingfinkle.org/specialthing;1" #define specialthing_classname "specialthing" #define specialthing_cid { 0x245626, 0x5cc1, 0x11db, { 0x96, 0x73, 0x0, 0xe0, 0x81, 0x61, 0x16, 0x5f } } class cspecialthing : public ispecialthing { public: ns_decl_isupports ns_decl_ispecialthing cspecialthing(); private: ~cspecialthing(); protected: /* additiona...

Components.Constructor
syntax var func = [ new ] components.constructor(contractid [, interfacename [, initializer ] ]); parameters contractid a
string containing the contract id of the component interfacename if given, nsisupports.queryinterface() will be called on each newly-created instance with the interface named by this
string initializer if given, a
string containing the name of a function which will be called on the newly-created instance, using the arguments provided to the created function when called description components.constructor() is a handy shortcut for creating instances of xpcom components.
...for example: var binaryinputstream = components.constructor("@mozilla.org/binaryinputstream;1"); var bis = new binaryinputstream(); print(bis.to
string()); // "[xpconnect wrapped nsisupports]" try { // someinputstream is an existing nsiinputstream // throws because bis hasn't been qi'd to nsibinaryinputstream bis.setinputstream(someinputstream); } catch (e) { bis.queryinterface(components.interfaces.nsibinaryinputstream); bis.setinputstream(someinputstream); // succeeds now } if two arguments are given, the created instance will be ...
...nsisupports.queryinterface()'d to the xpcom interface whose name is the second argument: var binaryinputstream = components.constructor("@mozilla.org/binaryinputstream;1", "nsibinaryinputstream"); var bis = new binaryinputstream(); print(bis.to
string()); // "[xpconnect wrapped nsibinaryinputstream]" // someinputstream is an existing nsiinputstream bis.setinputstream(someinputstream); // succeeds if three arguments are given, then in addition to being nsisupports.queryinterface()'d, the instance will also have had an initialization method called on it.

Using the Web Storage API - Web APIs
the keys and the values are always
strings (note that, as with objects, integer keys will be automatically converted to
strings).
...e (see events.js) the only javascript is as follows: window.addeventlistener('storage', function(e) { document.queryselector('.my-key').textcontent = e.key; document.queryselector('.my-old').textcontent = e.oldvalue; document.queryselector('.my-new').textcontent = e.newvalue; document.queryselector('.my-url').textcontent = e.url; document.queryselector('.my-storage').textcontent = json.
stringify(e.storagearea); }); here we add an event listener to the window object that fires when the storage object associated with the current origin is changed.
... as you can see above, the event object associated with this event has a number of properties containing useful information — the key of the data that changed, the old value before the change, the new value after that change, the url of the document that changed the storage, and the storage object itself (which we've
stringified so you can see its content).

string = "i love mdn"; ctx.filltext(text
string, x, y); monitoring screen resolution or zoom level changes in this example, we'll set up a media query and watch it to see when the device resolution changes, so that we can check the value of devicepixelratio to handle any updates we need to.
... let pixelratiobox = document.queryselector(".pixel-ratio"); let mq
string = `(resolution: ${window.devicepixelratio}dppx)`; const updatepixelratio = () => { let pr = window.devicepixelratio; let pr
string = (pr * 100).tofixed(0); pixelratiobox.innertext = `${pr
string}% (${pr.tofixed(2)})`; } updatepixelratio(); matchmedia(mq
string).addlistener(updatepixelratio); the
string mq
string is set up to be the media query itself.

string which displays the ratio both as a percentage and as a raw decimal value with up to two decimal places.
window.location - Web APIs

string of data to the server by modifying the search property: function senddata (sdata) { location.search = sdata; } // in html: <button onclick="senddata('some data');">send data</button> the current url with "?some%20data" appended is sent to the server (if no action is taken by the server, the current document is reloaded with the modified search
string).

string (similar to manipulating variable fonts with font-variation-settings).
...the example below shows a
string of glyphs with only the opentype set 'jis78' enabled.
...this gives a lot of control, but has some disadvantages in how it impacts inheritance and — as mentioned above — if you wish to change one setting, you have to redeclare the entire
string (unless you're using css custom properties to set the values).

Overview of events and handlers - Developer guides
the pattern starts with an agreement over a kind of event and: the name
string used for the event, the type of the data structure used to represent the key properties of that event, and the javascript object which will 'emit' that event.
... the pattern is implemented by defining a javascript function which takes as an argument the data structure which was agreed upon, and registering the function using the name
string with the object which will emit the event.
...browsers use as the registration method for the function which will handle those data structures a method called addeventlistener which expects as arguments a
string event type name and the handler function.

Quantifiers - JavaScript
notice that when matching "caaaaaaandy", the match is "aaa", even though the original
string had more "a"s in it.

Object.prototype.valueOf() - JavaScript
an object's valueof method is usually invoked by javascript, but you can invoke it yourself as follows: mynumbertype.valueof() note: objects in
string contexts convert via the to
string() method, which is different from
string objects converting to
string primitives using valueof.
... all objects have a
string conversion, if only "[object type]".
... examples using valueof on custom types function mynumbertype(n) { this.number = n; } mynumbertype.prototype.valueof = function() { return this.number; }; var myobj = new mynumbertype(4); myobj + 3; // 7 using unary plus +"5" // 5 (

RegExp.prototype.source - JavaScript
the source property returns a
string containing the source text of the regexp object, and it doesn't contain the two forward slashes on both sides and any flags.
... empty regular expressions and escaping starting with ecmascript 5, the source property no longer returns an empty
string for empty regular expressions.
... instead, the
string "(?:)" is returned.
RegExp.prototype.sticky - JavaScript
the sticky property reflects whether or not the search is sticky (searches in
strings only from the index indicated by the lastindex property of this regular expression).
...the "y" flag indicates that it matches only from the index indicated by the lastindex property of this regular expression in the target
string (and does not attempt to match from any later indexes).
... examples of correct behavior: var regex = /^foo/y; regex.lastindex = 2; regex.test('..foo'); // false - index 2 is not the beginning of the
string var regex2 = /^foo/my; regex2.lastindex = 2; regex2.test('..foo'); // false - index 2 is not the beginning of the
string or line regex2.lastindex = 2; regex2.test('.\nfoo'); // true - index 2 is the beginning of a line specifications specification ecmascript (ecma-262)the definition of 'regexp.prototype.sticky' in that specification.
RegExp.prototype.toSource() - JavaScript
the tosource() method returns a
string representing the source code of the object.
... syntax regexobj.tosource() return value a
string representing the source code of the given regexp object.
... examples native function for the built-in regexp object, tosource() returns the following
string indicating that the source code is not available: function regexp() { [native code] } for instances of regexp, tosource() returns a
string representing the source code.
Symbol.prototype.description - JavaScript
the read-only description property is a
string returning the optional description of symbol objects.
...it is different to symbol.prototype.to
string() as it does not contain the enclosing "symbol()"
string.

string(); // "symbol(mario)" to avoid name clashes with your global symbol keys and other (library code) global symbols, it might be a good idea to prefix your symbols: symbol.for('mdn.foo'); symbol.for('mdn.bar'); specifications specification ecmascript (ecma-262)the definition of 'symbol.for' in that specification.
Symbol.match - JavaScript
the symbol.match well-known symbol specifies the matching of a regular expression against a
string.
... this function is called by the
string.prototype.match() method.
...for example, the methods
string.prototype.startswith(),
string.prototype.endswith() and
string.prototype.includes(), check if their first argument is a regular expression and will throw a typeerror if they are.
Symbol.toPrimitive - JavaScript
the function is called with a
string argument hint, which specifies the preferred type of the result primitive value.
... the hint argument can be one of "number", "
string", and "default".
...var obj2 = { [symbol.toprimitive](hint) { if (hint == 'number') { return 10; } if (hint == '
string') { return 'hello'; } return true; } }; console.log(+obj2); // 10 -- hint is "number" console.log(`${obj2}`); // "hello" -- hint is "
string" console.log(obj2 + ''); // "true" -- hint is "default" specifications specification ecmascript (ecma-262)the definition of 'symbol.toprimitive' in that specification.
Symbol.prototype.toSource() - JavaScript

string representing the source code of the object.
... examples native function for the built-in symbol object, tosource returns the following
string indicating that the source code is not available: "function symbol() { [native code] }" for instances of symbol, tosource returns a
string representing the source code.
isNaN() - JavaScript
thus for non-numbers that when coerced to numeric type result in a valid non-nan numeric value (notably the empty
string and boolean primitives, which when coerced give numeric values zero or one), the "false" returned value may be unexpected; the empty
string, for example, is surely "not a number." the confusion stems from the fact that the term, "not a number", has a specific meaning for numbers represented as ieee-754 floating-point values.
... a polyfill for isnan would be (the polyfill leverages the unique never-equal-to-itself characteristic of nan): var isnan = function(value) { var n = number(value); return n !== n; }; examples isnan(nan); // true isnan(undefined); // true isnan({}); // true isnan(true); // false isnan(null); // false isnan(37); // false //
strings isnan('37'); // false: "37" is converted to the number 37 which is not nan isnan('37.37'); // false: "37.37" is converted to the number 37.37 which is not nan isnan("37,5"); // true isnan('123abc'); // true: parseint("123abc") is 123 but number("123abc") is nan isnan(''); // false: the empty

string in which hexadecimal escape sequences are replaced with the character that it represents.
... syntax unescape(str) parameters str a
string to be decoded.

string in which certain characters have been unescaped.
uneval() - JavaScript
the uneval() function creates a
string representation of the source code of an object.
... return value a
string representing the source code of object.

string containing 1 var b = '1'; uneval(b); // returns a
string containing "1" uneval(function foo() {}); // returns "(function foo(){})" var a = uneval(function foo() { return 'hi'; }); var foo = eval(a); foo(); // returns "hi" specifications not part of any standard.
Iteration protocols - JavaScript
}, [symbol.iterator]: function() { return this; } }; examples using the iteration protocols a
string is an example of a built-in iterable object: let some
string = 'hi'; console.log(typeof some
string[symbol.iterator]); // "function"
string's default iterator returns the
string's code points one by one: let iterator = some
string[symbol.iterator](); console.log(iterator + ''); // "[object
string iterator]" console.log(iterator.next()); // { value: "h", done: false } console.log(iterator.next()...
...); // { value: "i", done: false } console.log(iterator.next()); // { value: undefined, done: true } some built-in constructs—such as the spread syntax—use the same iteration protocol under the hood: console.log([...some
string]); // ["h", "i"] you can redefine the iteration behavior by supplying our own @@iterator: // need to construct a
string object explicitly to avoid auto-boxing let some
string = new
string('hi'); some
string[symbol.iterator] = function () { return { // this is the iterator object, returning a single element (the
string "bye") next: function () { return this._first ?
... { value: 'bye', done: (this._first = false) } : { done: true } }, _first: true }; }; notice how redefining @@iterator affects the behavior of built-in constructs that use the iteration protocol: console.log([...some
string]); // ["bye"] console.log(some
string + ''); // "hi" iterable examples built-in iterables
string, array, typedarray, map, and set are all built-in iterables, because each of their prototype objects implements an @@iterator method.

new operator - JavaScript
the following code adds a color property with value "original color" to all objects of type car, and then overwrites that value with the
string "black" only in the instance object car1.
...then the value of mycar.make is the
string "eagle", mycar.year is the integer 1993, and so on.
... car to include an owner property that takes a person object, as follows: function car(make, model, year, owner) { this.make = make; this.model = model; this.year = year; this.owner = owner; } to instantiate the new objects, you then use the following: var car1 = new car('eagle', 'talon tsi', 1993, rand); var car2 = new car('nissan', '300zx', 1992, ken); instead of passing a literal
string or integer value when creating the new objects, the above statements pass the objects rand and ken as the parameters for the owners.
for...in - JavaScript
the for...in statement iterates over all enumerable properties of an object that are keyed by
strings (ignoring ones keyed by symbols), including inherited enumerable properties.
...objects created from built–in constructors like array and object have inherited non–enumerable properties from object.prototype and
string.prototype, such as
string's indexof() method or object's to
string() method.
... examples using for...in the for...in loop below iterates over all of the object's enumerable, non-symbol properties and logs a
string of the property names and their values.
var - JavaScript
so you can just type: function foo() {
string('s') // note the function `
string` is implicitly visible } ...because globalthis.hasownproperty('
string') // true so the global object will ultimately be searched for unqualified identifiers.
... you don't have to type globalthis.
string, you can just type the unqualified
string.
...e assignment statement is reached: function do_something() { console.log(bar); // undefined var bar = 111; console.log(bar); // 111 } // ...is implicitly understood as: function do_something() { var bar; console.log(bar); // undefined bar = 111; console.log(bar); // 111 } examples declaring and initializing two variables var a = 0, b = 0; assigning two variables with single
string value var a = 'a'; var b = a; // ...is equivalent to: var a, b = a = 'a'; be mindful of the order: var x = y, y = 'a'; console.log(x + y); // undefineda here, x and y are declared before any code is executed, but the assignments occur later.

Async scripts for asm.js - Game development
what if your code is in a js
string?
... instead of using eval or innerhtml, both of which trigger synchronous compilation, you should use a blob with an object url: var blob = new blob([code
string]); var script = document.createelement('script'); var url = url.createobjecturl(blob); script.onload = script.onerror = function() { url.revokeobjecturl(url); }; script.src = url; document.body.appendchild(script); the setting of src rather than innerhtml is what makes this script async.
JSON - MDN Web Docs Glossary: Definitions of Web-related terms
json can represent numbers, booleans,
strings, null, arrays (ordered sequences of values), and objects (
string-value mappings) made up of these values (or of other arrays and objects).
... (date objects by default serialize to a
string containing the date in iso format, so the information isn't completely lost.) if you need json to represent additional data types, transform values as they are serialized or before they are deserialized.
Type - MDN Web Docs Glossary: Definitions of Web-related terms
for example, a boolean data type can hold only a true or false value at any given time, whereas a
string has the ability to hold a
string or a sequence of characters, a number can hold numerical values of any kind, and so on.
...for example, a value of type number can be multiplied by another number, but not by a
string - even if that
string contains only a number, such as the
string "2".
Accessible multimedia - Learn web development
chapter titles — chapter markers intended to help the user navigate the media resource implementing html5 video text tracks text tracks for displaying with html5 video need to be written in webvtt, a text format containing multiple
strings of text along with metadata such as what time in the video you want each text
string to be displayed, and even limited styling/positioning information.
... these text
strings are called cues.
What are hyperlinks? - Learn web development
links can correlate any text
string with a url, such that the user can instantly reach the target document by activating the link.
... deeper dive as we said, a link is a text
string tied to a url, and we use links to allow easy jumping from one document to another.
Basic native form controls - Learn web development
the coordinates are sent as two key/value pairs: the x value key is the value of the name attribute followed by the
string ".x".

Video and audio content - Learn web development
note: "transcribe" means "to write down spoken words as text." the resulting text is a "transcript." webvtt is a format for writing text files containing multiple
strings of text along with metadata such as the time in the video at which each text
string should be displayed, and even limited styling/positioning information.
... these text
strings are called cues, and there are several kinds of cues which are used for different purposes.
Choosing the right approach - Learn web development
single delayed operation repeating operation multiple sequential operations multiple simultaneous operations no yes no (unless it is the same one) no code example the following function creates a new date() object, extracts a time
string out of it using tolocaletime
string(), and then displays it in the ui.
... we then run it once per second using setinterval(), creating the effect of a digital clock that updates once per second (see this live, and also see the source): function displaytime() { let date = new date(); let time = date.tolocaletime
string(); document.getelementbyid('demo').textcontent = time; } const createclock = setinterval(displaytime, 1000); pitfalls the frame rate isn't optimized for the system the animation is running on, and can be somewhat inefficient.
Build your own function - Learn web development
type the following in your browser's javascript console, on any page you like: alert('this is a message'); the alert function takes a single argument — the
string that is displayed in the alert box.
... try varying the
string to change the message.
Drawing graphics - Learn web development
this is done using the htmlcanvaselement.getcontext() method, which for basic usage takes a single
string as a parameter representing the type of context you want to retrieve.
... both of these take three properties in their basic usage: the text
string to draw and the x and y coordinates of the point to start drawing the text at.
Inheritance in JavaScript - Learn web development
in this example, we've used template literals rather than
string concatenation to make the code easier to read.
...whenever you use various features of a web api , or methods/properties defined on a built-in browser object that you call on your
strings, arrays, etc., you are implicitly using inheritance.
Test your skills: JSON - Learn web development
the json is loaded into the page as a text
string and made available in the cat
string parameter of the displaycatinfo() function, called when the provided promise chain (which starts by fetching the json data) is fulfilled.
... you'll probably want to use an outer loop to loop through the cats and add their names to the motherinfo variable
string, and an inner loop to loop through all the kittens, add up the total of all/male/female kittens, and add those details to the kitteninfo variable
string.
JavaScript — Dynamic client-side scripting - Learn web development
after that, we discuss some key javascript features in detail, such as variables,
strings, numbers and arrays.
... introducing javascript objects in javascript, most things are objects, from core javascript features like
strings and arrays to the browser apis built on top of javascript.
Server-side web frameworks - Learn web development
every "view" function (a request handler) receives an httprequest object containing request information, and is required to return an httpresponse object with the formatted output (in this case a
string).
... # return httpresponse return httpresponse('output
string to return') route requests to the appropriate handler most sites will provide a number of different resources, accessible through distinct urls.
Getting started with React - Learn web development
you should see something like this logged: object { subject: "clarice" } the object property subject corresponds to the subject prop we added to our <app /> component call, and the
string clarice corresponds to its value.
...change the subject constant so that, instead of defining it as the
string react, you are reading the value of props.subject.
Command line crash course - Learn web development
note: to run a command with multiple options at the same time, you can usually put them all in a single
string after the dash character, for example ls -lah, or ls -ltrh.
... let’s say you had 1000 text files in a directory, and you wanted to go through them all and only delete the ones that have a certain sub
string inside the filename.

IPDL Best Practices
consider the following protocol: async protocol pasyncquerier { child: pasyncquery(); } async protocol pasyncquery { child: kickoffquery(ns
string query); parent: returnresult(ns
string result); __delete__(); } in this situation, there is a guaranteed sequence of messages that will be sent.
... it makes sense to fold construction and the first message together, as well as the penultimate and deletion messages, so that the final protocol looks like this: async protocol pasyncquerier { child: pasyncquery(ns
string query); } async protocol pasyncquery { parent: __delete__(ns
string result); } ...

Translation phase
this tool includes workspaces for translating
strings, reviewing
string submissions, and project dashboards.
...see the list of the most critical
strings for localizing in firefox, as well as a guide to understanding how they're organized.
Creating localizable web content
text content check that the text is factually correct for an international audience (e.g., mentions of en-us specific product pieces like specific search engines or dictionary should be adapted) look for
strings that are likely hard to translate because they are unclear, use play on words or colloquialisms.
... depending on context, find alternate
strings or document an explanation of the
string for localizers check that we don't link in new pages to sub-pages with anchors.
Localization formats
(it should be noted that this is near impossibility since most sites will be set up with gettext support.) .lang files can be easily edited in a text editor with this setup, a localizer is given a "[something].lang" file containing all the
strings needing localization.

Setting up the infrastructure
copy the shell scripts from /addons/trunk/site/app/locale/ to your locale directory: extract-po.sh will be used to extract all english
strings from your application's directories specified in source_dirs, merge the resulting template (*.pot) file with the existing (already containing translations) messages.po files for each locale (if they exist) and merge the new messages.po files to messages.mo files.
... stats-po.sh will give you a bird's-eye view on the statistics of translated, fuzzy and missing
strings for each locale.

Gecko Profiler FAQ
to stop the profiler from gathering more samples after the “startup end” marker that you’re interested in, you can call services.profiler.pause(); or you can insert a marker with a special
string and then write a script that filters out all samples that were gathered after your marker.
... this mode is usually recommended when you want to find a thread you want to do more focused profiling on, so that you can find its name and then construct a more useful thread filter
string based on the found thread name.

PLHashComparator
pl_compare
strings compare two character
strings using strcmp.
... see also pl_compare
strings, pl_comparevalues ...
PL_strlen
returns the length of a specified
string (not including the trailing '\0') syntax pruint32 pl_strlen(const char *str); parameter the function has these parameter: str size in bytes of item to be allocated.
... returns if successful, the function returns length of the specified
string.
PRDescIdentity
a
string may be associated with a layer when the layer is created.
... the
string is copied by the runtime, and pr_getnameforidentity returns a reference to that copy.
PR_GetLibraryName
syntax #include <prlink.h> char* pr_getlibraryname ( const char *dir, const char *lib); parameters the function has these parameters: dir a null-terminated
string representing the path name of the library, as returned by pr_getlibrarypath.
... returns if successful, returns a new character
string containing a constructed path name.
PR_NOT_REACHED
syntax #include <prlog.h> void pr_not_reached(const char *_reasonstr); parameters the macro has this parameter: reasonstr a
string that describes why you should not have reached this statement.
... returns nothing description this macro writes the specified reason
string to the log and terminates the application.
PR_SetErrorText
if not null, and if text is zero, the
string is assumed to be a null-terminated c
string.
... otherwise the text is assumed to be the length specified and to possibly include null characters (as might occur in a multilingual
string).
PR_cnvtf

JS_CompileScript
obsolete since jsapi 39 ascii or chars const char * or const char16_t *

...ascii and chars are the
string containing the text of the script.
JS_CompileScriptForPrincipals
src const char * or const jschar *
string containing the script to compile.
... src is the
string containing the text of the script.
JS_ConvertValue
type must be one of jstype_void, jstype_object, jstype_function, jstype_
string, jstype_number, or jstype_boolean.

string works like js::to
string.
JS_DecompileFunction
syntax js
string * js_decompilefunction(jscontext *cx, js::handle<jsfunction*> fun); name type description cx jscontext * pointer to a js context from which to derive runtime information.

string containing the text of the function.
JS_DecompileFunctionBody

string * js_decompilefunctionbody(jscontext *cx, js::handle<jsfunction*> fun, unsigned indent); name type description cx jscontext * the context in which to decompile the function.
...if successful, js_decompilefunctionbody returns a
string containing the source code of the function body.
JS_DefinePropertyWithTinyId
any time the javascript engine would pass the name of the property as a
string to the id parameter of a tiny-id-aware callback, it passes int_to_jsval(tinyid) instead.
...those getters and setters can use switch (jsval_to_int(id)), instead of checking the value of id as a
string, to determine which property is being accessed.
JS_EvaluateScript
src const char * or const jschar *
string containing the script to compile and execute.
... src is the
string containing the text of the script.
JS_EvaluateScriptForPrincipals
src / bytes / chars const char * or const jschar
string containing the script to compile and execute.
... src is the
string containing the text of the script.
JS_FS
the _sym variants allow defining a function with a symbol key rather than a
string key.
...(in builds without es6 symbols, it defines a method with the
string id "@@iterator".) see an example in the jsapi user guide.
JS_ForgetLocalRoot
this must point to a jsobject, js
string, jsfunction, or jsdouble.
...(here the term gc-thing refers to any value that is subject to garbage collection: a jsobject, js
string, jsfunction, or jsdouble.) js_forgetlocalroot works on any gc-thing allocated in the current local root scope, but it's more time-efficient when called on references to more recently created gc-things.
JS_LookupElement
note: in the javascript language, numeric properties (also called "elements") are just ordinary properties whose names are numeric

...js_strdup allocates a copy of the null-terminated
string s.
Property attributes
mxr id search for jsprop_shared jsprop_index the property's id is represented internally as an integer, not a
string.
... obsolete since jsapi 39 this flag has an additional special meaning when used with js_defineproperty, js_fs, and other apis that define properties: it means that the name parameter is actually an integer unsafely cast to a pointer type, not a
string.

Using C struct and pointers
using c
strings with js-ctypes a pointer to char in javascript is declared as follows: var str = ctypes.pointertype(ctypes.char); now imagine you call a c function that returns a c
string and you want to modify the contents of this
string.
... once we have a ctypes char pointer that points to a buffer of known size, we modiify the contents of the memory block as follows: ptr.contents =
string("hello world from javascript!!!");
string() adds the '\0' character.
Declaring types
field descriptors each field descriptor is comprised of a field name and its data type, represented as a
string and a ctype object, respectively.
... var timestr = asctime(thetime.address()); // pass a pointer to the tm struct var js
string = timestr.read
string(); // convert the c
string to javascript the last line converts the c
string returned by the libc asctime() function into a javascript
string by calling the cdata read
string() method.

string passed to eval() or as a
string passed to the function constructor.

...for example, in the screenshot above you can see that javascript objects account for most memory, followed by
strings.

Monster example - Firefox Developer Tools
each monster has: a
string, for the monster's name a number representing the number of eyes it has a number representing the number of tentacles it has.

JavaScript technologies overview - JavaScript
among other things, ecmascript defines: language syntax (parsing rules, keywords, control flow, object literal initialization, ...) error handling mechanisms (throw, try...catch, ability to create user-defined error types) types (boolean, number,
string, function, object, ...) the global object.
...the internationalization api provides collation (
string comparison), number formatting, and date-and-time formatting for javascript applications, letting the applications choose the language and tailor the functionality to their needs.
Memory Management - JavaScript

SyntaxError: missing formal parameter - JavaScript
in the declaration of a function, the parameters must be identifiers, not any value like numbers,
strings, or objects.
...an identifier differs from a
string in that a
string is data, while an identifier is part of the code.
SyntaxError: missing ; before statement - JavaScript
however, oftentimes, this error is only a consequence of another error, like not escaping
strings properly, or using var wrongly.
... examples unescaped
strings this error can occur easily when not escaping
strings properly and the javascript engine is expecting the end of your
string already.

string against which a regular expression is matched.
... the value of the input property is modified whenever the searched
string on the regular expression is changed and that
string is matching.
RegExp.leftContext ($`) - JavaScript
the non-standard leftcontext property is a static and read-only property of regular expressions that contains the sub
string preceding the most recent match.
... you can not use the shorthand alias with the dot property accessor (regexp.$`), because the parser expects a starting template
string in that case and a syntaxerror is thrown.

Nullish coalescing operator (??) - JavaScript
0; console.log(vala); // "default for a" console.log(valb); // "" (as the empty
string is not null or undefined) console.log(valc); // 42 assigning a default value to a variable earlier, when one wanted to assign a default value to a variable, a common pattern was to use the logical or operator (||): let foo; // foo is never assigned any value so it is still undefined let somedummytext = foo || 'hello!'; however, due to || being a boolean logical operator, the left hand-side ...
... let count = 0; let text = ""; let qty = count || 42; let message = text || "hi!"; console.log(qty); // 42 and not 0 console.log(message); // "hi!" and not "" the nullish coalescing operator avoids this pitfall by only returning the second operand when the first one evaluates to either null or undefined (but no other falsy values): let mytext = ''; // an empty
string (which is also a falsy value) let notfalsytext = mytext || 'hello world'; console.log(notfalsytext); // hello world let preservingfalsy = mytext ??
Spread syntax (...) - JavaScript
spread syntax (...) allows an iterable such as an array expression or
string to be expanded in places where zero or more arguments (for function calls) or elements (for array literals) are expected, or an object expression to be expanded in places where zero or more key-value pairs (for object literals) are expected.
... syntax for function calls: myfunction(...iterableobj); for array literals or
strings: [...iterableobj, '4', 'five', 6]; for object literals (new in ecmascript 2018): let objclone = { ...obj }; rest syntax (parameters) rest syntax looks exactly like spread syntax.
this - JavaScript
primitives like 7 or 'foo' will be converted to an object using the related constructor, so the primitive number 7 is converted to an object as if by new number(7) and the
string 'foo' to an object as if by new
string('foo'), e.g.
... function bar() { console.log(object.prototype.to
string.call(this)); } bar.call(7); // [object number] bar.call('foo'); // [object
string] bar.call(undefined); // [object global] the bind method ecmascript 5 introduced function.prototype.bind().
for...of - JavaScript
the for...of statement creates a loop iterating over iterable objects, including: built-in
string, array, array-like objects (e.g., arguments or nodelist), typedarray, map, set, and user-defined iterables.
... const iterable = [10, 20, 30]; for (let value of iterable) { value += 1; console.log(value); } // 11 // 21 // 31 iterating over a
string const iterable = 'boo'; for (const value of iterable) { console.log(value); } // "b" // "o" // "o" iterating over a typedarray const iterable = new uint8array([0x00, 0xff]); for (const value of iterable) { console.log(value); } // 0 // 255 iterating over a map const iterable = new map([['a', 1], ['b', 2], ['c', 3]]); for (const entry of iterable) { console.log(entry); } // ['a', 1...

string needs to be constructed dynamically.
Strict mode - JavaScript
eval code, function code, event handler attributes,
strings passed to windowtimers.settimeout(), and related functions are entire scripts, and invoking strict mode in them works as expected.
...for a normal function, this is always an object: either the provided object if called with an object-valued this; the value, boxed, if called with a boolean,
string, or number this; or the global object if called with an undefined or null this.
JavaScript
the complete modules available there are as follows: javascript first steps answers some fundamental questions such as "what is javascript?", "what does it look like?", and "what can it do?", along with discussing key javascript features such as variables,

stringarray[0] = "hi".
Rhino history
also, the implementation effectively leaked memory since most jvms don't really collect unused classes or the
strings that are interned as a result of loading a class file.

Performance Hints
for example, the code function myobject(a) { this.s = a; this.to
string = new function("return this.s"); } could be written more efficiently as function myobject(a) { this.s = a; this.to
string = function () { return this.s } } beginning with rhino 1.4 release 2, code passed to eval and new function will be interpreted rather than compiled to class files.

Common (exsl) - EXSLT
this lets you process the xml created within a variable to process it in multiple steps.exsl:object-type()exsl:object-type() returns a
string that indicates the type of the specified object.
math:highest() - EXSLT
a node has this maximum value if converting its
string value to a number equals the maximum value.
math:lowest() - EXSLT
a node has this minimum value if converting its
string value to a number equals the minimum value.
math:max() - EXSLT
returns a result tree fragment representing the highest valued node's numeric value as a
string.
math:min() - EXSLT
returns a result tree fragment representing the lowest valued node's numeric value as a
string.
Regular expressions (regexp) - EXSLT
regexp:match()regexp:match() performs regular expression matching on a
string, returning the submatches found as a result.regexp:replace()regexp:replace() replaces the portions of a
string that match a given regular expression with the contents of another
string.regexp:test()regexp:test() tests to see whether a
string matches a specified regular expression.
Sets (set) - EXSLT
in other words, it returns a node-set whose nodes are in one node-set but not in the other.set:distinct()set:distinct() returns a subset of the nodes in the specified node-set, returning only nodes with unique
string values.set:has-same-node()set:has-same-node() determines whether two node-sets have any nodes in common.set:intersection()set:intersection() returns the intersection of two node-sets.

Constraint validation - Developer guides
basically, the idea is to trigger javascript on some form field event (like onchange) to calculate whether the constraint is violated, and then to use the method field.setcustomvalidity() to set the result of the validation: an empty
string means the constraint is satisfied, and any other
string means there is an error and this
string is the error message to display to the user.
Writing forward-compatible websites - Developer guides
don't ua-sniff this is really a particularly common instance of assuming that one feature (the presence of a particular sub
string in the user agent (ua)
string) implies something about the presence or absence of other features.
HTTP range requests - HTTP
each part contains its own content-type and content-range fields and the required boundary parameter specifies the boundary
string used to separate each body-part.
Redirections in HTTP - HTTP
javascript redirections redirections in javascript are performed by setting a url
string to the window.location property, loading the new page: window.location = "https://example.com/"; like html redirections, this can't work on all resources, and obviously, this will only work on clients that execute javascript.
Introduction - JavaScript
in contrast to java's compile-time system of classes built by declarations, javascript supports a runtime system based on a small number of data types representing numeric, boolean, and
string values.
Iterators and generators - JavaScript
t) // can iterate many times it[symbol.iterator] = function* () { yield 2; yield 1; }; user-defined iterables you can make your own iterables like this: const myiterable = { *[symbol.iterator]() { yield 1; yield 2; yield 3; } } for (let value of myiterable) { console.log(value); } // 1 // 2 // 3 or [...myiterable]; // [1, 2, 3] built-in iterables
string, array, typedarray, map and set are all built-in iterables, because their prototype objects all have a symbol.iterator method.
Unicode property escapes - JavaScript
note: for unicode property escapes to work, a regular expression must use the u flag which indicates a

string' (num is set to '') test(null) // 'object' (num is set to null) evaluated at call time the default argument is evaluated at call time.
getter - JavaScript
note the following when working with the get syntax: it can have an identifier which is either a number or a
string; it must have exactly zero parameters (see incompatible es5 change: literal getter and setter functions must now have exactly zero or one arguments for more information); it must not appear in an object literal with another get or with a data entry for the same property ({ get x() { }, get x() { } } and { x: ..., get x() { } } are forbidden).
setter - JavaScript
note the following when working with the set syntax: it can have an identifier which is either a number or a
string; it must have exactly one parameter (see incompatible es5 change: literal getter and setter functions must now have exactly zero or one arguments for more information); it must not appear in an object literal with another set or with a data entry for the same property.
Array.prototype.concat() - JavaScript
data types such as
strings, numbers and booleans (not
string, number, and boolean objects): concat copies the values of
strings and numbers into the new array.
Array.isArray() - JavaScript
if (!array.isarray) { array.isarray = function(arg) { return object.prototype.to
string.call(arg) === '[object array]'; }; } examples using array.isarray // all following calls return true array.isarray([]); array.isarray([1]); array.isarray(new array()); array.isarray(new array('a', 'b', 'c', 'd')); array.isarray(new array(3)); // little known fact: array.prototype itself is an array: array.isarray(array.prototype); // all following calls return false array.isarray(); array.
Array.prototype.shift() - JavaScript
it also displays the removed element: var myfish = ['angel', 'clown', 'mandarin', 'surgeon']; console.log('myfish before:', json.
stringify(myfish)); // myfish before: ['angel', 'clown', 'mandarin', 'surgeon'] var shifted = myfish.shift(); console.log('myfish after:', myfish); // myfish after: ['clown', 'mandarin', 'surgeon'] console.log('removed this element:', shifted); // removed this element: angel using shift() method in while loop the shift() method is often used in condition inside while loop.
Array.prototype.some() - JavaScript
g an arrow function const fruits = ['apple', 'banana', 'mango', 'guava']; function checkavailability(arr, val) { return arr.some(arrval => val === arrval); } checkavailability(fruits, 'kela'); // false checkavailability(fruits, 'banana'); // true converting any value to boolean const truthy_values = [true, 'true', 1]; function getboolean(value) { 'use strict'; if (typeof value === '

Promise - JavaScript
// it doesn't have to be a
string, but if it is only a succeed message, it probably will be.
Proxy - JavaScript
y if (prop === 'latestbrowser') { return obj.browsers[obj.browsers.length - 1]; } // the default behavior to return the value return obj[prop]; }, set: function(obj, prop, value) { // an extra property if (prop === 'latestbrowser') { obj.browsers.push(value); return true; } // convert the value if it is not an array if (typeof value === '

string (by mistake) console.log(products.browsers); // ['firefox'] <- no problem, the value is an array products.latestbrowser =...
RangeError - JavaScript
this can be encountered when: passing a value that is not one of the allowed
string values to
string.prototype.normalize(), or when attempting to create an array of an illegal length with the array constructor, or when passing bad values to the numeric methods number.prototype.toexponential(), number.prototype.tofixed() or number.prototype.toprecision().
Reflect.apply() - JavaScript
examples using reflect.apply() reflect.apply(math.floor, undefined, [1.75]); // 1; reflect.apply(
string.fromcharcode, undefined, [104, 101, 108, 108, 111]) // "hello" reflect.apply(regexp.prototype.exec, /ab/, ['confabulation']).index // 4 reflect.apply(''.charat, 'ponies', [3]) // "i" specifications specification ecmascript (ecma-262)the definition of 'reflect.apply' in that specification.

string.prototype specifications specification ecmascript (ecma-262)the definition of 'reflect.getprototypeof' in that specification.
Reflect.has() - JavaScript
examples using reflect.has() reflect.has({x: 0}, 'x') // true reflect.has({x: 0}, 'y') // false // returns true for properties in the prototype chain reflect.has({x: 0}, 'to
string') // proxy with .has() handler method obj = new proxy({}, { has(t, k) { return k.startswith('door') } }); reflect.has(obj, 'doorbell') // true reflect.has(obj, 'dormitory') // false reflect.has returns true for any inherited properties, like the in operator: const a = {foo: 123} const b = {__proto__: a} const c = {__proto__: b} // the prototype chain is: c -> b -> a reflect.has(c, 'foo')...
Reflect.ownKeys() - JavaScript

strings in insertion order, // symbols in insertion order specifications specification ecmascript (ecma-262)the definition of 'reflect.ownkeys' in that specification.
RegExp.prototype.compile() - JavaScript
flags if specified, flags can have any combination of the following values: g global match i ignore case m multiline; treat beginning and end characters (^ and $) as working over multiple lines (i.e., match the beginning or end of each line (delimited by \n or \r), not only the very beginning or end of the whole input
string) y sticky; matches only from the index indicated by the lastindex property of this regular expression in the target
string (and does not attempt to match from any later indexes).
RegExp.prototype.dotAll - JavaScript
the "s" flag indicates that the dot special character (".") should additionally match the following line terminator ("newline") characters in a
string, which it would not match otherwise: u+000a line feed (lf) ("\n") u+000d carriage return (cr) ("\r") u+2028 line separator u+2029 paragraph separator this effectively means the dot will match any character on the unicode basic multilingual plane (bmp).
RegExp.lastParen ($+) - JavaScript
the non-standard lastparen property is a static and read-only property of regular expressions that contains the last parenthesized sub
string match, if any.
Set - JavaScript
console.log([...myset]) // will show you exactly the same array as myarray remove duplicate elements from the array // use to remove duplicate elements from the array const numbers = [2,3,4,4,2,3,3,4,4,5,5,6,6,7,5,32,3,4,5] console.log([...new set(numbers)]) // [2, 3, 4, 5, 6, 7, 32] relation with
strings let text = 'india' let myset = new set(text) // set ['i', 'n', 'd', 'i', 'a'] myset.size // 5 //case sensitive & duplicate ommision new set("firefox") // set(7) [ "f", "i", "r", "e", "f", "o", "x" ] new set("firefox") // set(6) [ "f", "i", "r", "e", "o", "x" ] specifications specification ecmascript (ecma-262)the definition of 'set' in that specification.
Symbol.iterator - JavaScript
the built-in types with a @@iterator method are: array.prototype[@@iterator]() typedarray.prototype[@@iterator]()
string.prototype[@@iterator]() map.prototype[@@iterator]() set.prototype[@@iterator]() see also iteration protocols for more information.
undefined - JavaScript
// don't do this // logs "foo
string" (function() { var undefined = 'foo'; console.log(undefined, typeof undefined); })(); // logs "foo
string" (function(undefined) { console.log(undefined, typeof undefined); })('foo'); examples strict equality and undefined you can use undefined and the strict equality and inequality operators to determine whether a variable has a value.
Addition assignment (+=) - JavaScript
syntax operator: x += y meaning: x = x + y examples using addition assignment // assuming the following variables // foo = 'foo' // bar = 5 // baz = true // number + number -> addition bar += 2 // 7 // boolean + number -> addition baz += 1 // 2 // boolean + boolean -> addition baz += false // 1 // number +
string -> concatenation bar += 'foo' // "5foo" //
string + boolean -> concatenation foo += false // "foofalse" //
string +
string -> concatenation foo += 'bar' // "foobar" specifications specification ecmascript (ecma-262)the definition of 'assignment operators' in that specification.
Destructuring assignment - JavaScript
a trailing comma is used on the left-hand side with a rest element: const [a, ...b,] = [1, 2, 3]; // syntaxerror: rest element may not have a trailing comma // always consider using rest operator as the last element unpacking values from a regular expression match when the regular expression exec() method finds a match, it returns an array containing first the entire matched portion of the
string and then the portions of the
string that matched each parenthesized group in the regular expression.

Unary plus (+) - JavaScript
it can convert
string representations of integers and floats, as well as the non-

yield* - JavaScript
.log(iterator.next()); // {value: 2, done: false} console.log(iterator.next()); // {value: 3, done: false} console.log(iterator.next()); // {value: 4, done: false} console.log(iterator.next()); // {value: 5, done: false} console.log(iterator.next()); // {value: undefined, done: true} other iterable objects besides generator objects, yield* can also yield other kinds of iterables (e.g., arrays,
strings, or arguments objects).
for await...of - JavaScript
the for await...of statement creates a loop iterating over async iterable objects as well as on sync iterables, including: built-in
string, array, array-like objects (e.g., arguments or nodelist), typedarray, map, set, and user-defined async/sync iterables.
if...else - JavaScript
any value that is not false, undefined, null, 0, -0, nan, or the empty
string (""), and any object, including a boolean object whose value is false, is considered truthy when used as the condition.
