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 domstrings introduction as web applications become more and more powerful, adding features such as audio and video manipulation, access to raw data using websockets, and so forth, it has become clear that there are times when...
...in the past, this had to be simulated by treating the raw data as a string and using the
charcodeat() method to read the bytes from the data buffer.

...in the above example, the head is quite small: <head> <meta

Using C struct and pointers
declaring a js-ctypes struct matching a c struct if we have a c structure like this: struct st_t { void *self;
char *str; size_t buff_size; int i; float f;
char c; }; we can use it in javascript by writing something like this: var st_t = new ctypes.structtype("st_t", [ { "self": ctypes.pointertype(ctypes.void_t) }, { "str": ctypes.pointertype(ctypes.
char) }, { "buff_size": ctypes.size_t }, { "i": ctypes.int }, { "f": ctypes.float }, { "c": ctypes.
char } ]); here we are using the structtype() factory method of the ctypes object to create a ctype obj...
... 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.
...additionally, the js-ctypes pointer must be casted to reflect the size of the buffer: var ptr = ctypes.cast( str, ctypes.arraytype( ctypes.
char, buff_size ).ptr ); here buff_size is of type ctypes.size_t.
... 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
you can then declare and use a function that uses this structure, like this: // declare the libc asctime() function, which returns a
char * and accepts a pointer to a tm structure.
... const asctime = lib.declare("asctime", ctypes.default_abi, ctypes.
char.ptr, struct_tm.ptr); var thetime = new struct_tm; thetime.tm_hour = 3; thetime.tm_min = 15; ...
...ect indicating the type to which the pointer should refer: const intptr = new ctypes.pointertype(ctypes.int); in this example, intptr is equivalent to this declaration in c: typedef int *intptr; you can similarly declare a pointer type as a pointer to any user-defined type, including structures: const userrecord = new ctypes.structtype("userrecord", [{"name": ctypes.
char.ptr}, {"id": ctypes.int32}]); const userrecordptr = new ctypes.pointertype(userrecord); in this example, a new userrecord type is defined, along with a new pointer type that can be used to reference it.
... the equivalent c code looks like this: typedef struct userrecord {
char *name; int id; // assuming int is 32-bit here } userrecord; typedef userrecordptr *userrecord; ...

characters (i.e.,

Syntax - CSS: Cascading Style Sheets
it is important to note that even if a ruleset
characterized by a group of selectors is a kind of shorthand replacing rulesets with a single selector each, this doesn't apply to the validity of the ruleset itself.
...but there is other information that a web author wants to convey in the style sheet, like the
character set, other external style sheets to import, font face or list counter descriptions and many more.
... a statement is a building block that begins with any non-space
characters and ends at the first closing brace or semi-colon (outside a string, non-escaped and not included into another {}, () or [] pair).
...they are used to convey meta-data information (like @
charset or @import), conditional information (like @media or @document), or descriptive information (like @font-face).
conic-gradient() - CSS: Cascading Style Sheets
example conic gradients include pie
charts and color wheels.
...to use conic gradients to create pie
charts --- which is not the correct way to create pie
charts as background images are not accessible -- use hard color stops, where the color stop angles for two adjacent color stops are the same.
...while it is possible to create pie
charts, checkerboards, and other effects with conic gradients, css images provide no native way to assign alternative text, and therefore the image represented by the conic gradient will not be accessible to screen reader users.

character set is different from what they had anticipated.
... also, if you are not currently using utf-8, it's recommended that you switch to it in your web pages, as it simplifies
character handling in documents using different scripts.
... note that html5 restricts
character sets to those compatible with ascii and using at least 8 bits.

JS_MakeStringImmutable
description a string's
characters can never be changed, but spidermonkey uses two string optimization techniques behind the scenes: a growable string (see js_newgrowablestring ) has a buffer that the javascript engine can reallocate so that concatenating it with another string is much faster.
...in memory it is represented as a pointer to the other string and a pair of integers for the substring's starting point and length, rather than as a separate copy of all the
characters.
...(when an application shares a string by storing it in a javascript object that another thread can read, the javascript engine automatically makes the string thread-safe.) after a successful call to js_makestringimmutable, subsequent calls to js_getstring
charsz on the same string are guaranteed to succeed, and subsequent calls to js_getstring
chars on the same string are guaranteed to return a null-terminated string.

charset header the accept-
charset header indicates to the server what kinds of
character encodings are understood by the user-agent.
... with utf-8 now being well-supported, being the preferred way of encoding
characters, and to guarantee better privacy through less configuration-based entropy, browsers omit the accept-
charset header: internet explorer 8, safari 5, opera 11, firefox 10 and chrome 27 have abandoned this header.
Content-Type - HTTP

RegExp() constructor - JavaScript
patterns may include special
characters to match a wider range of values than would a literal string.
... flags may contain any combination of the following
characters: g (global match) find all matches rather than stopping after the first match.
... m (multiline) treat beginning and end
characters (^ and $) as working over multiple lines.
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).
... to allow it to match astral
characters, the "u" (unicode) flag should be used.
... using both flags in conjunction allows the dot to match any unicode
character, without exceptions.
String.prototype.endsWith() - JavaScript
the endswith() method determines whether a string ends with the
characters of a specified string, returning true or false as appropriate.
... syntax str.endswith(searchstring[, length]) parameters searchstring the
characters to be searched for at the end of str.
... return value true if the given
characters are found at the end of the string; otherwise, false.
String.prototype.lastIndexOf() - JavaScript
fromindex optional the index of the last
character in the string to be considered as the beginning of a match.
... description
characters in a string are indexed from left to right.
... the index of the first
character is 0, and the index of the last
character is str.length - 1.
String length - JavaScript
utf-16, the string format used by javascript, uses a single 16-bit code unit to represent the most common
characters, but needs to use two code units for less commonly-used
characters, so it's possible for the value returned by length to not match the actual number of
characters in the string.
... unicode since `length` counts code units instead of
characters, if you want to get the number of
characters you need something like this: function get

String.raw() - JavaScript
examples using string.raw() string.raw`hi\n${2+3}!`; // 'hi\n5!', the
character after 'hi' // is not a newline
character, // '\' and 'n' are two
characters.
... string.raw`hi\u000a!`; // 'hi\u000a!', same here, this time we will get the // \, u, 0, 0, 0, a, 6
characters.
... // all kinds of escape
characters will be ineffective // and backslashes will be present in the output string.
String.prototype.slice() - JavaScript
the
character at this index will not be included.
...str.slice(1, 4) extracts the second
character through the fourth
character (
characters indexed 1, 2, and 3).
... as an example, str.slice(2, -1) extracts the third
character through the second to last
character in the string.
String.prototype.startsWith() - JavaScript
the startswith() method determines whether a string begins with the
characters of a specified string, returning true or false as appropriate.
... syntax str.startswith(searchstring[, position]) parameters searchstring the
characters to be searched for at the start of this string.
... return value true if the given
characters are found at the beginning of the string; otherwise, false.
decodeURI() - JavaScript
exceptions throws an urierror ("malformed uri sequence") exception when encodeduri contains invalid
character sequences.
... description replaces each escape sequence in the encoded uri with the
character that it represents, but does not decode escape sequences that could not have been introduced by encodeuri.
... the
character “#” is not decoded from escape sequences.
unescape() - JavaScript
warning: although unescape() is not strictly deprecated (as in "removed from the web standards"), it is defined in annex b of the ecma-262 standard, whose introduction states: … all of the language features and behaviours specified in this annex have one or more undesirable
characteristics and in the absence of legacy usage would be removed from this specification.
...… the unescape() function computes a new string in which hexadecimal escape sequences are replaced with the
character that it represents.
... return value a new string in which certain
characters have been unescaped.
Destructuring assignment - JavaScript
setting a function parameter's default value function draw
chart({size = 'big', coords = {x: 0, y: 0}, radius = 25} = {}) { console.log(size, coords, radius); // do some
chart drawing } draw
chart({ coords: {x: 18, y: 30}, radius: 30 }); in the function signature for draw
chart above, the destructured left-hand side is assigned to an empty object literal on the right-hand side: {size = 'big', coords = {x: 0, y: 0}, radius = 25} = {}.
...however, if you leave out the right-hand side assignment, the function will look for at least one argument to be supplied when invoked, whereas in its current form, you can simply call draw
chart() without supplying any parameters.
...etadata; console.log(englishtitle); // "scratchpad" console.log(localetitle); // "javascript-umgebung" for of iteration and destructuring const people = [ { name: 'mike smith', family: { mother: 'jane smith', father: 'harry smith', sister: 'samantha smith' }, age: 35 }, { name: 'tom jones', family: { mother: 'norah jones', father: 'ri

... 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.
Property - MDN Web Docs Glossary: Definitions of Web-related terms
it may refer to: property (css) a css property is a
characteristic (like color) whose associated value defines one aspect of how the browser should display the element.

HTML: A good basis for accessibility - Learn web development
apart from this, you should try to avoid using language and
characters that don't get read out clearly by the screen reader.
...for example, there is a longdesc attribute that is meant to point to a separate web document containing an extended description of the image, for example: <img src="dinosaur.png" longdesc="dino-info.html"> this sounds like a good idea, especially for infographics like big
charts with lots of information on them that could perhaps be represented as an accessible data table instead (see accessible data tables).

What is accessibility? - Learn web development
if you are planning to include a whizzy 3d pie
chart graphic made using webgl, you might want to include a data table as an accessible alternative representation of the data.
... or, you might want to just include the table and get rid of the 3d pie
chart — the table is accessible by everyone, quicker to code, less cpu-intensive, and easier to maintain.
Type, class, and ID selectors - Learn web development
class selectors the class selector starts with a full stop (.)
character and will select everything in the document with that class applied to it.
... id selectors an id selector begins with a # rather than a full stop
character, but is basically used in the same way as a class selector.
Getting started with CSS - Learn web development
<!doctype html> <html lang="en"> <head> <meta

...your list will now look like this: <ul> <li>item one</li> <li class="special">item two</li> <li>item <em>three</em></li> </ul> in your css you can target the class of special by creating a selector that starts with a full stop
character.
Web fonts - Learn web development
a paid font distributor: this is a site that makes fonts available for a

...in newer browsers, you can also specify a unicode-range value, which is a specific range of
characters you want to use out of the web font — in supporting browsers, only the specified
characters will be downloaded, saving unnecessary downloading.
What is a URL? - Learn web development
if the path part of the url starts with the "/"
character, the browser will fetch that resource from the top root of the server, without reference to the context given by the current document.
...you've probably often seen urls that look like mashups of random
characters.
Test your skills: Form validation - Learn web development
give the "user name" field a required length of between 5 and 20
characters, the "phone number" field a maximum length of 15
characters, and the "comment" field a maximum length of 200
characters.
... make the input mandatory to fill in, and give it a minimum length of 10
characters.
Test your skills: Other controls - Learn web development
give the comments a maximum length of 100
characters.
... associate the list with your text input, so that when you type
characters, any of the list options that match the
character sequence are given in a dropdown list as autocomplete suggestions.
Dealing with files - Learn web development
some servers will replace the areas in your filenames with "%20" (the
character code for spaces in uris), resulting in all your links being broken.
... <!doctype html> <html> <head> <meta
charset="utf-8"> <title>my test page</title> </head> <body> <img src="" alt="my test image"> </body> </html> the line <img src="" alt="my test image"> is the html code that inserts an image into the page.

Working with Svelte stores - Learn web development
our alert component will displayed by the app component, but any component can send notifications to it; whenever a notification arrives the alert component will be in
charge of displaying it on screen.
... this is a perfect example of how svelte puts the compiler in
charge of better developer ergonomics, not only saving us from typing boiler plate, but also generating less error-prone code.
Package management basics - Learn web development
create index.html in your test directory, and give it the following contents: <!doctype html> <html lang="en-us"> <head> <meta
charset="utf-8"> <title>my test page</title> </head> <body> <script src="./index.js"></script> </body> </html> next, we need to add an index.js file in the same directory as index.html.
... the range is specified in the version of the dependency in your package.json, such as date-fns@^2.0.1 — in this case the caret
character ^ means all minor and patch releases after and including 2.0.1, up to but excluding 3.0.0.
Mozilla accessibility architecture
each platform's accessibility api has made different assumptions, although there are a number of common
characteristics.
...note: this
chart is not complete, consult the handleevent() method to see the rest.
Accessibility information for UI designers and developers
for example, in this
chart, it helps to add labels besides the colored
chart lines:people who cannot see the difference between the colors, can use the labels instead.
...on desktop with a keyboard, it lets people type a
character, say ‘k’, to jump directly to options starting with ‘k’.
Eclipse CDT Manual Setup
if you want a column marker to mark the 80th column to help with formatting code to mozilla's 80
character line limit, tick "show print margin" and set the value to 80.
...(sadly, there is no auto-activation option to activate autocomplete suggestion., so as soon as you type any alphabetical
character that may begin with a symbol name like there is in other ides.) select "c/c++ > editor > save actions" and deselect "ensure newline at the end of file".

... when you create a bug, if you want the person in
charge of the l10n to follow up your bug you should cc: l10n@mozilla.com if you choose to make changes to your localization, you should make the changes local to your disk, push them to your hg repository on merucial, test the changes on a nightly/tinderbox build, fix any errors if some are found and test again, and send the new changeset id as your "opt-in" revisions to the l10-drivers.
I/O Functions
nspr uses unix-style pathnames, which are null-terminated
character strings.
... only the ascii
character set is supported.
PL_CompareStrings
compares two
character strings.
... syntax #include <plhash.h> printn pl_comparestrings( const void *v1, const void *v2); description pl_comparestrings compares v1 and v2 as
character strings using strcmp.
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_NetAddrToString
converts a
character string to a network address.
... syntax #include <prnetdb.h> prstatus pr_netaddrtostring( const prnetaddr *addr,
char *string, pruint32 size); parameters the function has the following parameters: addr a pointer to the network address to be converted.
PR_SetErrorText
syntax #include <prerror.h> void pr_seterrortext(printn textlength, const
char *text) parameters the function has these parameters: textlength the length of the text in the text.
...otherwise the text is assumed to be the length specified and to possibly include null
characters (as might occur in a multilingual string).
NSS Certificate Download Specification
the begin and end lines must begin and end with 5 dashes, with no extra leading or trailing white space (excluding the end of line
characters).
...therefore it is important to ensure that no extra
characters, such as nulls or linefeeds are added at the end of the object.

it displays the results for each run side by side, or vertically if the browser window is narrow: the results for each run are summarised in a table and a pie
chart.
...the accompanying pie
chart shows the relative size of each resource type.
Network request list - Firefox Developer Tools
you can filter by plain text (in which case the text is used to find partial matches; entering "for" will match any message that contains the word "for") or—as of firefox 75—using regular expressions (by writing the regexp bracketed within slashes; "/.+corp.*/" will look for any occurrence of "corp" which has at least one
character before it and may or may not have any
characters after it, for example).
... --globoff suppresses curl's globbing (wildcard matching) feature if the copied url includes square bracket
characters ([ or ]).

chart tells you the call stack at any given point during the recording: to learn much more about the flame
chart, see the separate flame
chart page.
Performance - Firefox Developer Tools
you get four sub-tools to examine aspects of the profile in more detail: the waterfall shows the different operations the browser was performing, such as executing layout, javascript, repaints, and garbage collection the call tree shows the javascript functions in which the browser spent most of its time the flame

characterdata and documenttype implemented the new interfaces.
console - Web APIs
ng a single object the simplest way to use the logging methods is to output a single object: var someobject = { str: "some text", id: 5 }; console.log(someobject); the output looks something like this: [09:27:13.475] ({str:"some text", id:5}) outputting multiple objects you can also output multiple objects by simply listing them when calling the logging method, like this: var car = "dodge
charger"; var someobject = { str: "some text", id: 5 }; console.info("my first car was a", car, ".
... the object is:", someobject); this output will look like this: [09:28:22.711] my first car was a dodge

word-spacing - CSS: Cascading Style Sheets
<percentage> specifies extra spacing as a percentage of the affected
character’s advance width.
... legible word-spacing must be determined on a case-by-case basis, as different font families have different
character widths.

Event developer guide - Developer guides
events refers both to a design pattern used for the asynchronous handling of various incidents which occur in the lifetime of a web page and to the naming,
characterization, and use of a large number of incidents of different types.
...unfortunately, these events have been defined piece by piece as web browsers have evolved so that there is no satisfying systematic
characterization of the events built-in or defined by modern web browsers.
Content categories - Developer guides
every html element is a member of one or more content categories — these categories group elements that share common
characteristics.
...canvas>, <cite>, <code>, <command>, <data>, <datalist>, <dfn>, <em>, <embed>, <i>, <iframe>, <img>, <input>, <kbd>, <keygen>, <label>, <mark>, <math>, <meter>, <noscript>, <object>, <output>, <picture>, <progress>, <q>, <ruby>, <samp>, <script>, <select>, <small>, <span>, <strong>, <sub>, <sup>, <svg>, <textarea>, <time>, <var>, <video>, <wbr> and plain text (not only consisting of white spaces
characters).
Printing - Developer guides
open and automatically close a popup window when finished if you want to be able to automatically close a popup window (for example, the printer-friendly version of a document) after the user prints its contents, you can use code like this: <!doctype html> <html> <head> <meta http-equiv="content-type" content="text/html;

character, comment, <script> element or <style> element.
... onhashchange function to call when the fragment identifier part (starting with the hash ('#')
character) of the document's current address has changed.
<input type="hidden"> - HTML: Hypertext Markup Language
additional attributes in addition to the attributes common to all <input> elements, hidden inputs offer the following attributes: attribute description name like all input types, the name of the input to report when submitting the form; the special value _
charset_ causes the hidden input's value to be reported as the
character encoding used to submit the form name this is actually one of the common attributes, but it has a special meaning available for hidden inputs.
...however, when the form is submitted, a hidden input whose name is set to _
charset_ will automatically be reported with the value set to the
character encoding used to submit the form.
<input type="number"> - HTML: Hypertext Markup Language
if the control's content has one directionality (ltr or rtl) but needs to present the placeholder in the opposite directionality, you can use unicode bidirectional algorithm formatting
characters to override directionality within the placeholder; see overriding bidi using unicode control
characters in the unicode bidirectional text algorithm for those
characters.
... important: bear in mind that, logically, you should not be able to enter
characters inside a number input other than numbers.
<rb>: The Ruby Base element - HTML: Hypertext Markup Language
usage notes ruby annotations are for showing pronunciation of east asian
characters, like using japanese furigana or taiwanese bopomofo
characters.
... examples in this example, we provide an annotation for the original
character equivalent of "kanji": <ruby> <rb>漢<rb>字 <rp>(</rp><rt>kan<rt>ji<rp>)</rp> </ruby> note how we've included two <rb> elements, to delimit the two separate parts of the ruby base text.

<xmp> - HTML: Hypertext Markup Language
the html2 specification recommended that it should be rendered wide enough to allow 80
characters per line.
...note that you will need to escape the '<'
character as '<' to make sure it is not interpreted as markup.
lang - HTML: Hypertext Markup Language
a 2-or-3-
character code that defines the basic language, typically written in all lowercase.
...this subtag defines the writing system used for the language, and is always 4
characters long, with the first letter capitalized.
Content-Disposition - HTTP
a name with a value of '_
charset_' indicates that the part is not an html field, but the default
charset to use for parts without explicit
charset information.

Equality comparisons and sameness - JavaScript
unfortunately, object.is simply has to be thought of in terms of its specific
characteristics, rather than its looseness or strictness with regard to the equality operators.
... nan false false false false nan nan false false true true when to use object.is versus triple equals in general, the only time object.is's special behavior towards zeros is likely to be of interest is in the pursuit of certain meta-programming schemes, especially regarding property descriptors, when it is desirable for your work to mirror some of the
characteristics of object.defineproperty.
Indexed collections - JavaScript
using this
characteristic of javascript arrays, multi-dimensional arrays can be created.
... function printarguments() { array.prototype.foreach.call(arguments, function(item) { console.log(item); }); } array prototype methods can be used on strings as well, since they provide sequential access to their
characters in a similar way to arrays: array.prototype.foreach.call('a string', function(chr) { console.log(chr) }) typed arrays javascript typed arrays are array-like objects and provide a mechanism for accessing raw binary data.
Working with objects - JavaScript
the same way, javascript objects can have properties, which define their
characteristics.
...the properties of an object define the
characteristics of the object.

SyntaxError: unterminated string literal - JavaScript
the + operator variant looks like this: var longstring = 'this is a very long string which needs ' + 'to wrap across multiple lines because ' + 'otherwise my code is unreadable.'; or you can use the backslash
character ("\") at the end of each line to indicate that the string will continue on the next line.
... make sure there is no space or any other
character after the backslash (except for a line break), or as an indent; otherwise it will not work.
Intl.Locale.prototype.numeric - JavaScript
the intl.locale.prototype.numeric property is an accessor property that returns whether the locale has special collation handling for numeric
characters.
...if numeric is set to true, then the locale will take numeric
characters into account when collating strings.
Intl - JavaScript
for example: "hi": hindi (language) "de-at": german (language) as used in austria (region) "zh-hans-cn": chinese (language) written in simplified
characters (script) as used in china (region) "en-emodeng": english (language) in the "early modern english" dialect (variant) the subtags identifying languages, scripts, regions (including countries), and (rarely used) variants in unicode bcp 47 locale identifiers are registered in the iana language subtag registry.

String.prototype.indexOf() - JavaScript
description
characters in a string are indexed from left to right.
... the index of the first
character is 0, and the index of the last
character of a string called stringname is stringname.length - 1.
String.prototype.replace() - JavaScript
using an inline function that modifies the matched
characters in this example, all occurrences of capital letters in the string are converted to lower case, and a hyphen is inserted just before the match location.
... let newstring = propertyname.replace(/[a-z]/g, '-' + '$&'.tolowercase()); // won't work this is because '$&'.tolowercase() would first be evaluated as a string literal (resulting in the same '$&') before using the
characters as a pattern.
<mfenced> - MathML
separators a sequence of zero or more
characters to be used for different separators, optionally divided by white space, which is ignored.
...by specifying more than one
character, it is possible to set different separators for each argument in the expression.
Web audio codec guide - Web media technologies
example: voice recording and playback the specific
characteristics of human speech allow speech-specific codecs to compress the audio far more than most general-purpose codecs can.
...fortunately, the
characteristics that lead to speech codecs being so efficient storage space-wise also make them tend to be very low latency.

you may assign the same class name or names to any number of elements, however, multiple class names must be separated by whitespace
characters.
... white space in lists is defined as one or more of the following consecutive
characters: "space" (u+0020), "tab" (u+0009), "line feed" (u+000a), "carriage return" (u+000d), and "form-feed" (u+000c).
data-* - SVG: Scalable Vector Graphics
the * can be replaced by any
characters allowed in xml's rules for names, with the following restrictions: can't start with xml.
...hyphen
characters (-, u+002d) are removed and the next letter is capitalized, resulting in the camelcase format.
direction - SVG: Scalable Vector Graphics
it also may affect the direction in which
characters are positioned if the unicode-bidi property's value is either embed or bidi-override.
... it applies only to glyphs oriented perpendicular to the inline-base direction, which includes the usual case of horizontally-oriented latin or arabic text and the case of narrow-cell latin or arabic
characters rotated 90 degrees clockwise relative to a top-to-bottom inline-base direction.

JSString
conceptually, a javascript string is just an array of
char16_t
characters and a length.
JSVAL_IS_STRING
to access the content of a string jsval, use jsval_to_string, js_getstring
chars, and js_getstringlength.
JSVAL_TO_STRING
(the difference is that the latter will convert an object, array, number, or other value to a string in a type-safe way, creating a new string if needed.) to convert the return type of this macro (jsstring *) to a
char pointer, use js_getstringbytes.

examples forgotten closing curly bracket oftentimes, there is a missing curly bracket in your function code: var
charge = function() { if (sunny) { usesolarcells(); } else { promptbikeride(); }; correct would be: var

intl.locale.prototype.numeric returns whether the locale has special collation handling for numeric
characters.
Number.parseInt() - JavaScript
if the radix is smaller than 2 or bigger than 36, and the first non-whitespace
character cannot be converted to a number, nan is returned.
Object.is() - JavaScript
two values are the same if one of the following holds: both undefined both null both true or both false both strings of the same length with the same
characters in the same order both the same object (means both object have same reference) both numbers and both +0 both -0 both nan or both non-zero and both not nan and both have the same value this is not the same as being equal according to the == operator.
Reflect.apply() - JavaScript
examples using reflect.apply() reflect.apply(math.floor, undefined, [1.75]); // 1; reflect.apply(string.from
charcode, undefined, [104, 101, 108, 108, 111]) // "hello" reflect.apply(regexp.prototype.exec, /ab/, ['confabulation']).index // 4 reflect.apply(''.

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.exec() - JavaScript
description consider the following example: // match "quick brown" followed by "jumps", ignoring
characters in between // remember "brown" and "jumps" // ignore case let re = /quick\s(brown).+?(jumps)/ig; let result = re.exec('the quick brown fox jumps over the lazy dog'); the following table shows the results for this script: object property/index description example result [0] the full string of

syntax str.link(url) parameters url any string that specifies the href attribute of the <a> tag; it should be a valid url (relative or absolute), with any &
characters escaped as &, and any "
characters escaped as ".
String.prototype.match() - JavaScript
examples using match() in the following example, match() is used to find 'chapter' followed by 1 or more numeric
characters followed by a decimal point and numeric
character 0 or more times.
String.prototype.repeat() - JavaScript
but anyway, most current (august 2014) browsers can't handle // strings 1 << 28
chars or longer, so: if (str.length * count >= 1 << 28) throw new rangeerror('repeat count must not overflow maximum string size'); var maxcount = str.length * count; count = math.floor(math.log(count) / math.log(2)); while (count) { str += str; count--; } str += str.substring(0, maxcount - str.length); return str; } } examples using repeat 'abc'.r...
String.prototype.trim() - JavaScript
whitespace in this context is all the whitespace
characters (space, tab, no-break space, etc.) and all the line terminator
characters (lf, cr, etc.).
isNaN() - JavaScript
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" ...
Equality (==) - JavaScript
if the operands have the same type, they are compared as follows: string: return true only if both operands have the same
characters in the same order.
Object initializer - JavaScript
now you can use a similar syntax in object literals, too: // computed property names (es2015) let i = 0 let a = { ['foo' + ++i]: i, ['foo' + ++i]: i, ['foo' + ++i]: i } console.log(a.foo1) // 1 console.log(a.foo2) // 2 console.log(a.foo3) // 3 let param = 'size' let config = { [param]: 12, ['mobile' + param.
charat(0).touppercase() + param.slice(1)]: 4 } console.log(config) // {size: 12, mobilesize: 4} spread properties the rest/spread properties for ecmascript proposal (stage 4) adds spread properties to object literals.

for example: var b = new boolean(false); if (b) // this condition is truthy examples using if...else if (cipher_
char === from_
char) { result = result + to_
char; x++; } else { result = result + clear_
char; } using else if note that there is no elseif syntax in javascript.
