Encryption and Decryption - Archive of obsolete content
with most modern cryptography, the ability to keep encrypted information secret is based not on the cryptographic algorithm, which is widely known, but on a number called a
key that must be used with the algorithm to produce an encrypted result or to decrypt previously encrypted information.

this strategy allows nss to work with many hardware devices (e.g., to speed up the calculations required for cryptographic operations, or to access smartcards that securely protect a secret
key) and software modules (e.g., to allow to load such modules as a plugin that provides additional algorithms or stores
key or trust information) that implement the pkcs#11 interface.
... some cryptography uses the same secret
key for both encrypting and decrypting, for example password based encryption (pbe).
... this is often sufficient if you encrypt data for yourself, but as soon as you need to exchange signed/encrypted data with communication partners, using public
key encryption simplifies the
key management.

Signature (functions) - MDN Web Docs Glossary: Definitions of Web-related terms
a signature can include: parameters and their types a return value and type exceptions that might be thrown or passed back information about the availability of the method in an object-oriented program (such as the
keywords public, static, or prototype).
... public static void main(string[] args) the public
keyword is an access modifier and indicates that this method can be called by any object.
... the static
keyword indicates that this method is a class method as opposed to being an instance method.
... the void
keyword indicates that this method has no return value.
What is a URL? - Learn web development
summary with hypertext and http, url is one of the
key concepts of the web.
...let's see the most important parts using the following url: http://www.example.com:80/path/to/myfile.html?
key1=value1&
key2=value2#somewhereinthedocument http is the protocol.

you create a variable with the
keyword let (or var) followed by a name for your variable (you'll read more about the difference between the
keywords in a future article).
... constants are used to store values that are immutable or can't be changed and are created with the
keyword const.
...here we have defined a function by using the
keyword function, followed by a name, with parentheses put after it.
...the simplest form of conditional block starts with the

Inheritance in JavaScript - Learn web development
these are fairly easy to spot — in your own custom code, they are the members defined inside a constructor using the this.x = x type lines; in built in browser code, they are the members only available to object instances (usually created by calling a constructor using the new
keyword, e.g.
...for example, object.
keys().
... to create a subclass we use the extends
keyword to tell javascript the class we want to base our class on, class teacher extends person { constructor(subject, grade) { this.subject = subject; this.grade = grade; } } but there's a little catch.
... unlike old-school constructor functions where the new operator does the initialization of this to a newly-allocated object, this isn't automatically initialized for a class defined by the extends
keyword, i.e the sub-classes.

Using the Browser API
when you tap the url bar, you can enter a url using the built-in firefox os
keyboard (although note that we haven't implemented anything sophisticated in this app, like autofilling the http://, etc.).
... when you press the
keyboard's return button, the 'submit' event is fired, which we handle like this: urlform.addeventlistener('submit',function(e) { e.preventdefault(); browser.src = urlbar.value; urlbar.blur(); }); we first call preventdefault() to stop the form just submitting and reloading the page — which is really not what we want.
...finally, we call blur() on the url bar to stop focusing it, so the
keyboard moves off the screen, allowing us to get our full screen view back.
... that when it is submitted, the htmliframeelement.findall() method is used to do a search for the string entered into the search input element (searchbar) within the text of the current page (the second parameter can be changed to 'case-insensitive' if you want a case-insensitive search.) we then enable the previous and next buttons, set searchactive to true, and blur() the search bar to make the
keyboard disappear and stop taking up our screen once the search is submitted.

Creating JavaScript jstest reftests
this directory contains tests of spidermon
key conformance to ecmascript as well as spidermon
key non-standard extenstions to ecmascript.
... non262 tests the directory js/src/tests/non262/ should contain all tests of the following type: regressions of spidermon
key non-standard spidermon
key extensions to the javascript language test of "implementation-defined" details of the ecmascript standard for example, the exact definition of pi or some details of array sorting.
... performance tests or stress tests tests of spidermon
key's comformance to the ecmascript standard a brief history: in 2017, spidermon
key started comsuming test262, a comprehensive tests suite for ecmascript implementations.
... before using test262, spidermon
key had a fair number of internal tests of conformance to ecmascript, and many of those tests remain in the js/src/non262 directory as regressions.
Property cache
spidermon
key's property cache is an internal data structure used to speed up property accesses in the interpreter and to communicate between the interpreter and jit.
...spidermon
key mainly uses type inference to determine which properties are being accessed; in cases where type inference does not find the exact shape of the object being accessed, spidermon
key uses a pic (polymorphic inline caches) to store the result of the lookup.
... the hash table entries are
key-value pairs.
... the
keys describe the context in which a property lookup occurs.
JSNative
full documentation of how to define a jsnative (or a jsfastnative, the equivalent typedef which preceded it) is available in the api header "js/callargs.h" added in spidermon
key 24.
... this header is new, but the semantics it describes are applicable to all recent spidermon
key releases.
... the behavior of a jsnative is implemented using a js::callargs structure added in spidermon
key 17.
... (this structure is now provided in "js/callargs.h" added in spidermon
key 24 as well as through "jsapi.h".) this structure encapsulates access to the callee function, this, the function call's arguments, and the eventual return value.
JS_AlreadyHasOwnProperty

key 1.8.1 boo js_alreadyhasownelement(jscontext *cx, js::handleobject obj, uint32_t index, bool *foundp); name type description cx jscontext * pointer to a js context.
...for native objects—objects whose properties are stored in the default data structure provided by spidermon
key—these functions simply check that data structure to see if the specified field is present.
...(such properties are an implementation detail of spidermon
key.
JS_CStringsAreUTF8
these functions have been removed in spidermon
key 19.
... syntax jsbool js_cstringsareutf8(void); void js_setcstringsareutf8(void); // added in spidermon
key 1.8 description by default, all c/c++ strings passed into the jsapi are treated as iso/iec 8859-1, also known as iso-latin-1.
...however, spidermon
key can optionally interpret these strings as utf-8.
... there are two ways to enable this: at compile time, by building spidermon
key with js_c_strings_are_utf8 defined; or at run time, by calling js_setcstringsareutf8 before the first call to js_newruntime.

key allows for a distinction between system code (such as gcs, which may incidentally be triggered by script but are not strictly performed on behalf of such script), trusted script (as determined by js_settrustedprincipals), and untrusted script.
JS_THREADSAFE
the recommended technique in spidermon
key 1.8 and later is to periodically call js_yieldrequest from an operation callback.
... sharing native functions and private data among threads in a js_threadsafe build, spidermon
key's internal data structures that represent javascript values are single-thread-only.

Waterfall - Firefox Developer Tools
garbage collection red markers in the waterfall represent garbage collection (gc) events, in which spidermon
key (the javascript engine in firefox) walks the heap looking for memory that's no longer reachable and subsequently releasing it.
... to help reduce the length of pauses, spidermon
key implements incremental gc: this means that it can perform garbage collection in fairly small increments, letting the program run in between.
...spidermon
key uses a complex set of heuristics to determine when gc is needed, and when non-incremental gc in particular is needed.
... in general, though: gc is needed when a lot of memory is being allocated non-incremental gc is usually needed when the memory allocation rate is high enough that spidermon
key may run out of memory during incremental gc when the waterfall records a gc marker it indicates: whether the gc was incremental or not the reason the gc was performed if the gc was non-incremental, the reason it was non-incremental starting in firefox 46, if the gc event was caused by allocation pressure, a link appears, labeled "show allocation triggers".

URLSearchParams.sort() - Web APIs
the urlsearchparams.sort() method sorts all
key/value pairs contained in this object in place and returns undefined.
... the sort order is according to unicode code points of the
keys.
...the relative order between
key/value pairs with equal
keys will be preserved).

URL API - Web APIs
the url standard also defines concepts such as domains, hosts, and ip addresses, and also attempts to describe in a standard way the legacy application/x-www-form-urlencoded mime type used to submit web forms' contents as a set of
key/value pairs.
... other functions within urlsearchparams let you change the value of
keys, add and delete
keys and their values, and even sort the list of parameters.
...rows are added to the table, one for each
key found in the parameters, with the first column containing the
key's name, and the second column having the value.
... function filltablewithparameters(tbl) { let url = new url(document.location.href); url.searchparams.sort(); let

Web Animations API Concepts - Web APIs
animation objects accept media in the form of animation effects, specifically
keyframe effects (we’ll get to those in a moment).
... animation effect if animation objects are dvd players, we can think of animation effects, or
keyframe effects, as dvds.

... we currently have only one animation effect type available:
keyframeeffect.
Using XMLHttpRequest - Web APIs
note: starting with gecko 30.0 (firefox 30.0 / thunderbird 30.0 / seamon
key 2.27), synchronous requests on the main thread have been deprecated due to the negative effects to the user experience.
... note: the non-standard sendasbinary method is considered deprecated as of gecko 31 (firefox 31 / thunderbird 31 / seamon
key 2.28) and will be removed soon.
... using formdata objects the formdata constructor lets you compile a set of
key/value pairs to send using xmlhttprequest.
... its primary use is in sending form data, but can also be used independently from a form in order to transmit user
keyed data.
Using the link role - Accessibility
native <a> elements also support
keyboard and focus requirements by default, without need for additional customization.
...this includes javascript to grab the location and handle navigating to the new location using window.open() via clicking, and using
keyboard, css to give the desired visuals of a link, the tabindex="0" attribute to make it
keyboard-focussable, and role="link" to make it recognised as a link by assistive technology.
... id="link1" role="link" class="link"> fake accessible link created using a span </span> <p><a href="https://mozilla.org" target="_blank">actual real link</a></p> css span[role="link"] { color: blue; text-decoration: underline; cursor: pointer; } span[role="link"]:focus { outline: 1px dotted black; } javascript const spanelem = document.queryselector('span'); //handles clicks and
keydowns on the link function navigatelink(e) { if (e.type === 'click' || e.
key === 'enter') { let ref = e.target != null ?
... e.target : e.srcelement; if (ref) { window.open(ref.getattribute('data-href'), '_blank'); } } } spanelem.addeventlistener('click', navigatelink); spanelem.addeventlistener('
keydown', navigatelink); result notes if pressing the link triggers an action but does not change browser focus or navigate to a new page, you might wish to consider using the button role instead of the link role.
ARIA: timer role - Accessibility
keyboard interactions
keyboard interaction is xxx.

Ordering Flex Items - CSS: Cascading Style Sheets
flexbox and the
keyboard navigation disconnect html source order vs css display order the responsive order conflict for
keyboard focus use cases for order there are sometimes places where the fact that the logical and therefore reading order of flex items is separate from the visual order, is helpful.
...the heading of the news item is the
key thing to highlight and would be the element that a user might jump to if they were tabbing between headings to find content they wanted to read.
...when doing so take care that you are not reordering items that could be accessed by the
keyboard as a user is tabbing around.
... especially when using newer layout methods you should ensure that your browser testing includes testing the site using
keyboard only, rather than a mouse or touchscreen.

Applying color to HTML elements using CSS - HTML: Hypertext Markup Language
keywords a set of standard color names have been defined, letting you use these
keywords instead of numeric representations of colors if you choose to do so and there's a
keyword representing the exact color you want to use.
... color
keywords include the standard primary and secondary colors (such as red, blue, or orange), shades of gray (from black to white, including colors like darkgray and lightgrey), and a variety of other blended colors including lightseagreen, cornflowerblue, and rebeccapurple.
... see color
keywords in <color> for a list of all available color
keywords.

<input type="password"> - HTML: Hypertext Markup Language
specifics of how the entry process works may vary from browser to browser; mobile devices, for example, often display the typed character for a moment before obscuring it, to allow the user to be sure they pressed the
key they meant to press; this is helpful given the small size of
keys and the ease with which the wrong one can be pressed, especially on virtual
keyboards.
... <label for="userpassword">password: </label> <input id="userpassword" type="password" required> <input type="submit" value="submit"> specifying an input mode if your recommended (or required) password syntax rules would benefit from an alternate text entry interface than the standard
keyboard, you can use the inputmode attribute to request a specific one.
...mobile devices with virtual
keyboards, for example, may opt to switch to a numeric
keypad layout instead of a full
keyboard, to make entering the password easier.
... the inputmode is set to numeric to encourage devices with virtual
keyboards to switch to a numeric
keypad layout for easier entry.
<input type="reset"> - HTML: Hypertext Markup Language
adding a reset
keyboard shortcut to add a
keyboard shortcut to a submit button — just as you would with any <input> for which it makes sense — you use the access
key global attribute.
... in this example, r is specified as the access
key (you'll need to press r plus the particular modifier
keys for your browser/os combination; see access
key for a useful list of those).
... <form> <div> <label for="example">type in some sample text</label> <input id="example" type="text"> </div> <div> <input type="reset" value="reset the form" access
key="r"> </div> </form> the problem with the above example is that there's no way for the user to know what the access
key is!
...when building a site, be sure to provide this information in a way that doesn't interfere with the site design (for example by providing an easily accessible link that points to information on what the site access
keys are).
HTML elements reference - HTML: Hypertext Markup Language
common uses for this element are to implement a glossary or to display metadata (a list of
key-value pairs).
... <kbd> the html
keyboard input element (<kbd>) represents a span of inline text denoting textual user input from a
keyboard, voice input, or any other text entry device.
... <
keygen> the html <

Browser detection using the user agent - HTTP
do you actually want to detect firefox, as opposed to seamon
key, or chrome as opposed to chromium?
...so to detect safari you have to check for the safari string and the absence of the chrome string, chromium often reports itself as chrome too or seamon

Configuring servers for Ogg media - HTTP
include regular
key frames when the browser seeks through ogg media to a specified time, it has to seek to the nearest
key frame before the seek target, then download and decode the video from there until the requested target time.
... the farther apart your
key frames are, the longer this takes, so it's helpful to include
key frames at regular intervals.
... by default, ffmpeg2theora uses one
key frame every 64 frames (or about every 2 seconds at 30 frames per second), which works pretty well.
... note: of course, the more
key frames you use, the larger your video file is, so you may need to experiment a bit to get the right balance between file size and seek performance.

Arrow function expressions - JavaScript
an arrow function expression is a syntactically compact alternative to a regular function expression, although without its own bindings to the this, arguments, super, or new.target
keywords.
... two factors influenced the introduction of arrow functions: the need for shorter functions and the behavior of the this
keyword.
... var foo = () => {}; console.log(foo.prototype); // undefined use of the yield
keyword the yield
keyword may not be used in an arrow function's body (except when permitted within functions further nested within it).
...foo is treated like a label, not a
key in an object literal).
Functions - JavaScript
in the case of a constructor called with the new
keyword, the default value is the value of its this parameter.
... */ console.log(mycar.brand); the this
keyword does not refer to the currently executing function, so you must refer to function objects by name, even within the function body.
... as we can see, both examples do not start with the function
keyword.
...however, in the spidermon
key javascript engine, the serialized form of the function shows as if it has the name "anonymous".

key-value pairs into an object.
... description the object.fromentries() method takes a list of
key-value pairs and returns a new object whose properties are given by those entries.
... the iterable argument is expected to be an object that implements an @@iterator method, that returns an iterator object, that produces a two element array-like object, whose first element is a value that will be used as a property

Understanding WebAssembly text format - WebAssembly
let's start by doing this — first, we'll add a name preceded by a dollar sign, just after the func
keyword: (func $add … ) now we need to add an export declaration — this looks like so: (export "add" (func $add)) here, add is the name the function will be identified by in javascript whereas $add picks out which webassembly function inside the module is being exported.
... our github repo; also see global.html for a live javascript example): (module (global $g (import "js" "global") (mut i32)) (func (export "getglobal") (result i32) (global.get $g)) (func (export "incglobal") (global.set $g (i32.add (global.get $g) (i32.const 1)))) ) this looks similar to what we've seen before, except that we specify a global value using the
keyword global, and we also specify the
keyword mut along with the value's datatype if we want it to be mutable.
... the
key is that javascript can create webassembly linear memory instances via the webassembly.memory() interface, and access an existing memory instance (currently you can only have one per module instance) using the associated instance methods.
...initialization object now has a shared property, which when set to true will create a shared memory: let memory = new webassembly.memory({initial:10, maximum:100, shared:true}); the memory's buffer property will now return a sharedarraybuffer, instead of the usual arraybuffer: memory.buffer // returns sharedarraybuffer over in the text format, you can create a shared memory using the shared
keyword, like this: (memory 1 2 shared) unlike unshared memories, shared memories must specify a "maximum" size, in both the javascript api constructor and wasm text format.

JavaScript Object Management - Archive of obsolete content
a clear example of this is the fact that there are no private or public
keywords that allow you to protect object members.
...we only need to define them when we're making windows of our own, or when we're working with code outside of the chrome (or porting your code to seamon
key, which doesn't have those constants declared in the main window).
...using the function
keyword to define a class is odd, but this is just the javascript way: functions are also objects.

Security best practices in extensions - Archive of obsolete content
this is written from the perspective of a firefox extension, but most items apply to extensions for other mozilla-based applications such as thunderbird or seamon
key.
...the usefulness of it and power of how it works is best illustrated by the popular greasemon
key extension, which works on the premise of scripts being downloaded and stored locally, to be injected into the web content context via the sandbox.
... many extensions use the greasemon
key compiler to bundle it in their extension for convenience.

keys (ex: ctrl) are being held.
... notification when a tab's attributes change requires gecko 2.0(firefox 4 / thunderbird 3.3 / seamon

Implementing game control mechanisms - Game development
in this series of articles we will show you how you can approach building a game that can be played using touchscreen smartphones, mouse and
keyboard, and also less common mechanisms such as gamepads.
... in the following articles we will show how to implement various different control mechanisms for captain rogers to support different platforms — from touch on mobile, through
keyboard/mouse/gamepad on desktop, to more unconventional ones like tv remote, shouting to or waving your hand in front of the laptop, or squeezing bananas.
... desktop mouse and
keyboard controls — when playing on a desktop/laptop computer, providing
keyboard and mouse controls is essential to provide an acceptable level of accessibility for the game.
Mouse controls - Game development
we have already added
keyboard controls, but we could easily add mouse controls too.
... listening for mouse movement listening for mouse movement is even easier than listening for
key presses: all we need is the listener for the mousemove event.
... add the following line in the same place as the other event listeners, just below the
keyup event: document.addeventlistener("mousemove", mousemovehandler, false); anchoring the paddle movement to the mouse movement we can update the paddle position based on the pointer coordinates — the following handler function will do exactly that.
2D maze game with device orientation - Game development
now we will add the ability to control the ball with the

... let’s focus on the
keyboard first by adding the following to the create() function : this.
keys = this.game.input.
keyboard.createcursor
keys(); as you can see there’s a special phaser function called createcursor
keys(), which will give us an object with event handlers for the four arrow
keys to play with: up, down, left and right.
...the this.
keys object will be checked against player input, so the ball can react accordingly with the predefined force: if(this.
keys.left.isdown) { this.ball.body.velocity.x -= this.movementforce; } else if(this.
keys.right.isdown) { this.ball.body.velocity.x += this.movementforce; } if(this.
keys.up.isdown) { this.ball.body.velocity.y -= this.movementforce; } else if(this.
keys.down.isdown) { this.ball.body.velocity.y += this.movementforce; } that way we can check which
key is pressed at the given frame and apply the defined force to the ball, thus increase the velocity in the proper direction.

Beginner's guide to media queries - Learn web development
media queries are a
key part of responsive web design, as they allow you to create different layouts depending on the size of the viewport, but they can also be used to detect other things about the environment your site is running on, for example whether the user is using a touchscreen rather than a mouse.
...this feature means you can test if the user has the ability to hover over an element, which essentially means they are using some kind of pointing device; touchscreen and
keyboard navigation does not hover.
...the value none means the user has no pointing device; perhaps they are navigating with the
keyboard only or with voice commands.

Adding a new CSS property
(note that when the longhand property css_property_parse_value_list, the shorthand property parser would be assumed to be reusing the longhand parser once per item, not for a whole list, as for properties like background-image or transform-timing-function.) if the property takes a list of
keywords other than inherit/initial/etc., auto, none, or normal (which can be expressed using the variant_* flags), you should use variant_
keyword and add a
keyword table to the nscssprops class.
... the name of this
keyword table needs to go in the nscssproplist entry; otherwise that
keyword table should be null.
... if you need a
keyword table, you should include auto, normal, or none (if needed) in that table rather than combining variant_
keyword with variant_auto, variant_normal, or variant_none.

key releases.
... neither of these functions is quite like the javascript new

JS_GET_CLASS
this macro was removed in spidermon
key 1.8.8 when the signature of js_getclass() was changed to take only an object pointer.

JS_GetParent
an object created by a script via the new
keyword has the same parent as the constructor.
... an object's parent serves two purposes in spidermon
key: for some functions, it is used to implement lexical scoping (but this is an implementation detail).

Browser Console - Firefox Developer Tools
from the
keyboard: press ctrl+shift+j (or cmd+shift+j on a mac).
... like the web console, the command line interpreter enables you to evaluate javascript expressions in real time:also like the web console's command line interpreter, this command line supports autocomplete, history, and various
keyboard shortcuts and helper commands.
...on windows, the following code will add a new item to the browser's main menu: var parent = window.document.getelementbyid("appmenuprimarypane"); var makethetea = gbrowser.ownerdocument.defaultview.document.createelementns("http://www.mozilla.org/

Set event listener breakpoints - Firefox Developer Tools
now when a
keydown,
keyup,
keypress, or input event occurs, execution will pause as soon as it enters the listener code.
... so if we choose to log
keyboard events, for example, the code no longer pauses as each event is fired: instead, we can then switch to the console, and whenever we press a
key we are given a log of where related events were fired.
... there's an issue here — the console is showing that the
keypress event is being fired somewhere inside jquery.
Network request list - Firefox Developer Tools
filtering by properties the search box recognizes specific
keywords, which can be used to filter the requests by specific request properties.
... those
keywords are followed by a colon and a related filter value.
...
keyword meaning examples status-code shows resources that have the specific http status code.
Allocations - Firefox Developer Tools
to reduce the impact on responsiveness, spidermon
key (the javascript engine in firefox) can perform gc in small increments, letting the program run in between.
...spidermon
key uses a complex set of heuristics to decide when to do what sort of garbage collection.
... in general, though: allocation pressure - allocating a lot of memory, or allocating memory at a high rate - makes spidermon
key more likely to run garbage collection, and more likely to run full, non-incremental garbage collection.
IndexedDB - Firefox Developer Tools
key — the
keypath property of the object store.
... auto increment — is automatic incrementation of the
keys enabled?
...all items have a
key and a value associated with them.
Storage Inspector - Firefox Developer Tools
opening the storage inspector you can open the storage inspector by selecting "storage inspector" from the web developer submenu in the firefox menu panel (or tools menu if you display the menu bar or are on macos), or by pressing its shift + f9
keyboard shortcut.
... a string containing a
key separated value, like "1~2~3~4" or "1=2=3=4" is shown like an array: [1, 2, 3, 4].
... a string containing
key-value pairs, like "id=1234:foo=bar" is shown as json: {id:1234, foo: "bar"}.
AesGcmParams - Web APIs
the aesgcmparams dictionary of the web crypto api represents the object that should be passed as the algorithm parameter into subtlecrypto.encrypt(), subtlecrypto.decrypt(), subtlecrypto.wrap

keywords have special meanings: _self: load the response into the same browsing context as the current one.
<dl>: The Description List element - HTML: Hypertext Markup Language
common uses for this element are to implement a glossary or to display metadata (a list of

key-value separator in the css, such as: dt::after { content: ": "; } wrapping name-value groups in <div> elements whatwg html allows wrapping each name-value group in a <dl> element in a <div> element.
<form> - HTML: Hypertext Markup Language
in html 4, this is the name/

<img>: The Image Embed element - HTML: Hypertext Markup Language
omitting alt altogether indicates that the image is a
key part of the content and no textual equivalent is available.
... setting this attribute to an empty string (alt="") indicates that this image is not a
key part of the content (it’s decoration or a tracking pixel), and that non-visual browsers may omit it from rendering.
...while this can provide additional information to the user, you should not assume that the user will ever see it: the user may only have
keyboard or touchscreen.
Link types - HTML: Hypertext Markup Language
note: you can also use the next
keyword to specify a link to the next page in the sequence.
...browsers, that don't have such a context will ignore this
keyword.
... if used in combination with the alternate
keyword, it defines an alternative style sheet; in that case the title attribute must be present and not be the empty string.
Identifying resources on the Web - HTTP
a more complex example might look like this: http://www.example.com:80/path/to/myfile.html?
key1=value1&
key2=value2#somewhereinthedocument urns a uniform resource name (urn) is a uri that identifies a resource by name in a particular namespace.
... query ?
key1=value1&
key2=value2 are extra parameters provided to the web server.
... those parameters are a list of
key/value pairs separated with the & symbol.
HTTP caching - HTTP
the primary cache
key consists of the request method and target uri (oftentimes only the uri is used as only get requests are caching targets).
... responses other than get if something suitable for use as a cache
key is defined.
... a cache entry might also consist of multiple stored responses differentiated by a secondary
key, if the request is target of content negotiation.
POST - HTTP
in this case, the content type is selected by putting the adequate string in the enctype attribute of the <form> element or the formenctype attribute of the <input> or <button> elements: application/x-www-form-urlencoded: the
keys and values are encoded in
key-value tuples separated by '&', with a '=' between the
key and the value.
... non-alphanumeric characters in both
keys and values are percent encoded: this is the reason why this type is not suitable to use with binary data (use multipart/form-data instead) multipart/form-data: each value is sent as a block of data ("body part"), with a user agent-defined delimiter ("boundary") separating each part.
... the
keys are given in the content-disposition header of each part.
Closures - JavaScript
you define some behavior, and then attach it to an event that is triggered by the user (such as a click or a

Details of the object model - JavaScript
inheriting properties suppose you create the mark object as a workerbee with the following statement: var mark = new workerbee; when javascript sees the new operator, it creates a new generic object and implicitly sets the value of the internal property [[prototype]] to the value of workerbee.prototype and passes this new object as the value of the this
keyword to the workerbee constructor function.
... the new operator passes the new object to the engineer constructor as the value of the this
keyword.
... because base is a method of engineer, within the call to base, javascript binds the this
keyword to the object created in step 1.

installation the api allows us to add event listeners for
key events we are interested in — the first one is the install event: self.addeventlistener('install', (e) => { console.log('[service worker] install'); }); in the install listener, we can initialize the cache and add files to it for offline use.
...the version number in the cache name is
key to this: var cachename = 'js13kpwa-v1'; when this updates to v2, we can then add all of our files (including our new files) to a new cache: contenttocache.push('/pwa-examples/js13kpwa/icons/icon-32.png'); // ...

Classes and Inheritance - Archive of obsolete content
to illustrate this, let's define a simple constructor for a class shape: function shape(x, y) { this.x = x; this.y = y; } we can now use this constructor to create instances of shape: let shape = new shape(2, 3); shape instanceof shape; // => true shape.x; // => 2 shape.y; // => 3 the
keyword new tells javascript that we are performing a constructor call.

Signature (security) - MDN Web Docs Glossary: Definitions of Web-related terms
from the hash of a given message, the signing process first generates a digital signature linked to the signing entity, using the entity's private

key to decrypt the signature and recover the hash, which can only be created with the sender's private
key, and checks message integrity - compares the hash with a newly calculated one from the received document (the two hashes will differ if the document has been tampered with) the system fails if the private
key is compromised or the recipient is deceitfully given the wrong public
key.

Cascade and inheritance - Learn web development
conflicting rules css stands for cascading style sheets, and that first word cascading is incredibly important to understand — the way that the cascade behaves is
key to understanding css.

this has different states depending on whether it is unvisited, visited, being hovered over, focused via the
keyboard, or in the process of being clicked (activated).
...or they might be using a screenreader, which reads out the content of the document, or they may need to use much larger text, or be navigating the site using the
keyboard only.
How CSS is structured - Learn web development
functions while most values are relatively simple
keywords or numeric values, there are some values which take the form of a function.

What is CSS? - Learn web development
this article explains what css is, with a simple syntax example, and also covers some
key terms about the language.

key thing about css is that everyone works very hard to never change things in a way that would break old websites.
CSS FAQ - Learn web development
initially css didn't provide a "default"
keyword and the only way to restore the default value of a property is to explicitly re-declare that property.
... for example: /* heading default color is black */ h1 { color: red; } h1 { color: black; } this has changed with css 2; the
keyword initial is now a valid value for a css property.
Styling links - Learn web development
focus: a link when it has been focused (for example moved to by a
keyboard user using the tab
key or similar, or programmatically focused using htmlelement.focus()) — this is styled using the :focus pseudo class.
... focused links have an outline around them — you should be able to focus on the links on this page with the
keyboard by pressing the tab
key (on mac, you'll need to use option + tab, or enable the full
keyboard access: all controls option by pressing ctrl + f7.) active links are red (try holding down the mouse button on the link as you click it.) interestingly enough, these default styles are nearly the same as they were back in the early days of browsers in the mid-1990s.

key/value pairs: the x value
key is the value of the name attribute followed by the string ".x".
... the y value
key is the value of the name attribute followed by the string ".y".
Sending forms through JavaScript - Learn web development
form data (application/x-www-form-urlencoded) is made of url-encoded lists of
key/value pairs.
... let's look at an example: <button>click me!</button> and now the javascript: const btn = document.queryselector('button'); function senddata( data ) { console.log( 'sending data' ); const xhr = new xmlhttprequest(); let urlencodeddata = "", urlencodeddatapairs = [], name; // turn the data object into an array of url-encoded
key/value pairs.
HTML basics - Learn web development
this includes things like
keywords and a page description that you want to appear in search results, css to style our content, character set declarations and more.
...if you save and reload the page, you should see something like this in place of the image: the
keywords for alt text are "descriptive text".
JavaScript basics - Learn web development
you start by declaring a variable with the var (less recommended, dive deeper for the explanation) or the let
keyword, followed by the name you give to the variable: let myvariable; note: a semicolon at the end of a line indicates where a statement ends.
...the words true and false are special
keywords that don't need quote marks.
Creating hyperlinks - Learn web development
note: a link title is only revealed on mouse hover, which means that people relying on
keyboard controls or touchscreens to navigate web pages will have difficulty accessing title information.
... search engines use link text to index target files, so it is a good idea to include
keywords in your link text to effectively describe what is being linked to.

Working with JSON - Learn web development
add the following at the bottom of your javascript code: let requesturl = 'https://mdn.github.io/learning-area/javascript/oojs/json/superheroes.json'; to create a request, we need to create a new request object instance from the xmlhttprequest constructor, using the new
keyword.
...the
key snippet of code is here: request.open('get', requesturl); request.responsetype = 'text'; // now we're getting a string!
Object-oriented JavaScript for beginners - Learn web development
notice also the this
keyword being used here as well — it is basically saying that whenever one of these object instances is created, the object's name property will be equal to the name value passed to the constructor call, and the greeting() method will use the name value passed to the constructor call too.
... let's look at the constructor calls again: let person1 = new person('bob'); let person2 = new person('sarah'); in each case, the new
keyword is used to tell the browser we want to create a new object instance, followed by the function name with its required parameters contained in parentheses, and the result is stored in a variable — very similar to how a standard function is called.
Object prototypes - Learn web development
object.is(), object.
keys(), and other members not defined inside the prototype bucket are not inherited by object instances or object types that inherit from object.prototype.
...the constructor is a function after all, so can be invoked using parentheses; you just need to include the new
keyword to specify that you want to use the function as a constructor.

Getting started with Ember - Learn web development
there are a couple of github issues open about this on the todomvc family of projects: add
keyboard access to demos re-enable outline on focusable elements ember has a strong commitment to being accessible by default and there is an entire section of the ember guides on accessibility on what it means for website / app design.
...lly, find app.css, located at app/styles/app.css, and paste in the following: :focus, .view label:focus, .todo-list li .toggle:focus + label, .toggle-all:focus + label { /* !important needed because todomvc styles deliberately disable the outline */ outline: #d86f95 solid !important; } this css overrides some of the styles provided by the todomvc-app-css npm package, therefore allowing
keyboard focus to be visible.

key bytecodes are the canonical form of code representation that is used in the javascript engine.
...bytecode listing was moved to spidermon
key internals: bytecode descriptions page.
JIT Optimization Strategies
spidermon
key's optimizing jit, ionmon
key, uses various strategies to optimize operations.
... optimization information is currently collected for the following operations: getproperty (obj.prop) setproperty (obj.prop = val) getelement (obj[elemname]) setelement (obj[elemname] = val) call (func(...)) at each operation site, ionmon
key tries a battery of strategies, from the most optimized but most restrictive to the least optimized but least restrictive.
JSAPI Cookbook

Iterators and generators - JavaScript
when a value is consumed by calling the generator's next method, the generator function executes until it encounters the yield
keyword.
...this simply means that the object (or one of the objects up its prototype chain) must have a property with a symbol.iterator
key.
Public class fields - JavaScript
public static fields are declared using the static
keyword.

keyword can be used to subclass custom classes as well as built-in objects.
TypeError: "x" is not a non-null object - JavaScript

in other words, there was an assignment without the var
keyword.
... function foo() { 'use strict'; bar = true; } foo(); // referenceerror: assignment to undeclared variable bar valid cases to make "bar" a declared variable, you can add the var
keyword in front of it.
TypeError: "x" is (not) "y" - JavaScript

keyfor(foo); // typeerror: foo is not a symbol var foo = 'bar' object.create(foo); // typeerror: "foo" is not an object or null fixing the issue to fix null pointer to undefined values, you can use the typeof operator, for example.
SyntaxError: function statement requires a name - JavaScript
you will need a few more braces in this case: (function () { })(); labeled functions if you are using function labels, you will still need to provide a function name after the function

...the following syntax without a name after the function
keyword is valid then.

keys get [property]() {}, set [property](value) {}, [property]( parameters… ) {}, *[generator]( parameters… ) {}, async [property]( parameters… ) {}, async* [generator]( parameters… ) {}, }; description the shorthand syntax is similar to the getter and setter syntax introduced in ecmascript 2015.
...(that is, * g(){} will work, but g *(){} will not.) non-generator method definitions cannot contain the yield
keyword.
Error() constructor - JavaScript
therefore, a mere call to error will produce the same output that constructing an error object via the new
keyword would.
...const y = new error('i was constructed via the "new"
keyword!') specifications specification ecmascript (ecma-262)the definition of 'error constructor' in that specification.
Error - JavaScript
examples throwing a generic error usually you create an error object with the intention of raising it using the throw
keyword.
... you can handle the error using the try...catch construct: try { throw new error('whoops!') } catch (e) { console.error(e.name + ': ' + e.message) } handling a specific error you can choose to handle only specific error types by testing the error type with the error's constructor property or, if you're writing for modern javascript engines, instanceof
keyword: try { foo.bar() } catch (e) { if (e instanceof evalerror) { console.error(e.name + ': ' + e.message) } else if (e instanceof rangeerror) { console.error(e.name + ': ' + e.message) } // ...
Function.prototype.bind() - JavaScript
the bind() method creates a new function that, when called, has its this
keyword set to the provided value, with a given sequence of arguments preceding any provided when the new function is called.
...const addthirtyseven = addarguments.bind(null, 37); const list2 = leadingthirtysevenlist(); // [37] const list3 = leadingthirtysevenlist(1, 2, 3); // [37, 1, 2, 3] const result2 = addthirtyseven(5); // 37 + 5 = 42 const result3 = addthirtyseven(5, 10); // 37 + 5 = 42 // (the second argument is ignored) with settimeout() by default within window.settimeout(), the this
keyword will be set to the window (or global) object.
Function.name - JavaScript
(new function).name; // "anonymous" anonymous function expression anonymous function expressions that were created using the
keyword function or arrow functions would have ""(an empty string) as their name.
...however, es2015 specifies the static
keyword such that static methods will be set as ownproperty of the class constructor function (ecmascript2015, 14.5.14.21.b + 12.2.6.9).

Intl - JavaScript
each constructor or function supports only a subset of the
keys defined for the unicode extension, and the supported values often depend on the language tag.
... for example, the "co"
key (collation) is only supported by collator, and its "phonebk" value is only supported for german.
Map() constructor - JavaScript
syntax new map([iterable]) parameters iterable an array or other iterable object whose elements are
key-value pairs.
... (for example, arrays with two elements, such as [[ 1, 'one' ],[ 2, 'two' ]].) each
key-value pair is added to the new map.

key) parameters target the target object in which to look for the property.
... property
key the name of the property to check.
Set.prototype.entries() - JavaScript
for set objects there is no
key like in map objects.
... however, to keep the api similar to the map object, each entry has the same value for its
key and value here, so that an array [value, value] is returned.
Symbol.asyncIterator - JavaScript
in order for an object to be async iterable, it must have a symbol.asynciterator
key.
... built-in async iterables there are currently no built-in javascript objects that have the [symbol.asynciterator]
key set by default.
WeakMap.prototype.delete() - JavaScript
syntax wm.delete(

key the
key of the element to remove from the weakmap object.
...false if the
key is not found in the weakmap or if the
key is not an object.
Iteration protocols - JavaScript
in order to be iterable, an object must implement the @@iterator method, meaning that the object (or one of the objects up its prototype chain) must have a property with a @@iterator
key which is available via constant symbol.iterator: property value [symbol.iterator] a zero-argument function that returns an object, conforming to the iterator protocol.
...therefore inside of the function, the this
keyword can be used to access the properties of the iterable object, to decide what to provide during the iteration.
Destructuring assignment - JavaScript
let
key = 'z'; let {[
key]: foo} = {z: 'bar'}; console.log(foo); // "bar" rest in object destructuring the rest/spread properties for ecmascript proposal (stage 4) adds the rest syntax to destructuring.
... rest properties collect the remaining own enumerable property
keys that are not already picked off by the destructuring pattern.
Property accessors - JavaScript
the
keys in this array are the names of the object's properties.
... let foo = {unique_prop: 1}, bar = {unique_prop: 2}, object = {}; object[foo] = 'value' console.log(object[bar]) in the spidermon
key javascript engine, this string would be "[object object]".
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.
... spread syntax (other than in the case of spread properties) can be applied only to iterable objects: const obj = {'
key1': 'value1'}; const array = [...obj]; // typeerror: obj is not iterable spread with many values when using spread syntax for function calls, be aware of the possibility of exceeding the javascript engine's argument length limit.
delete operator - JavaScript
-configurable properties that cannot be deleted with the delete operator: var nameother = 'xyz'; // we can access this global property using: object.getownpropertydescriptor(window, 'nameother'); // output: object {value: "xyz", // writable: true, // enumerable: true, // configurable: false} // since "nameother" is added using with the // var
keyword, it is marked as "non-configurable" delete nameother; // return false in strict mode, this would have raised an exception.
... if you want to use an ordered associative array in a cross-browser environment, use a map object if available, or simulate this structure with two separate arrays (one for the
keys and the other for the values), or build an array of single-property objects, etc.
void operator - JavaScript
e void operator should be taken into account and that parentheses can help clarify the resolution of the expression following the void operator: void 2 == '2'; // (void 2) == '2', returns false void (2 == '2'); // void (2 == '2'), returns undefined examples immediately invoked function expressions when using an immediately-invoked function expression, void can be used to force the function
keyword to be treated as an expression instead of a declaration.
... void function iife() { console.log("executed!"); }(); // output: "executed!" executing the above function without the void
keyword will result in an uncaught syntaxerror.
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.
...although arrays are often more practical for storing data, in situations where a
key-value pair is preferred for working with data (with properties acting as the "
key"), there may be instances where you want to check if any of those
keys hold a particular value.
for...of - JavaScript
alue 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] // ['b', 2] // ['c', 3] for (const [

keyword.
Template literals (Template strings) - JavaScript
function template(strings, ...
keys) { return (function(...values) { let dict = values[values.length - 1] || {}; let result = [strings[0]];
keys.foreach(function(
key, i) { let value = number.isinteger(
key) ?
... values[
key] : dict[
key]; result.push(value, strings[i + 1]); }); return result.join(''); }); } let t1closure = template`${0}${1}${0}!`; //let t1closure = template(["","","","!"],0,1,0); t1closure('y', 'a'); // "yay!" let t2closure = template`${0} ${'foo'}!`; //let t2closure = template([""," ","!"],0,"foo"); t2closure('hello', {foo: 'world'}); // "hello world!" let t3closure = template`i'm ${'name'}.

Animation performance and frame rate - Web Performance
with css animations you specify a number of
keyframes, each of which uses css to define the appearance of the element at a particular stage of the animation.
... the browser creates the animation as a transition from each
keyframe to the next.
CSS and JavaScript animation performance - Web Performance
css animations consist of two components: a style describing the css animation, and a set of
key frames that indicate the start and end states of the animation's style, as well as possible intermediate points.
...the
key is that as long as the properties we want to animate do not trigger reflow/repaint (read css triggers for more information), we can move those sampling operations out of the main thread.
Privacy, permissions, and information security
feature policy lets web developers selectively enable, disable, and modify the behavior of certain features and apis both for a document and for subdocuments loaded in <iframe>s <iframe>'s allow attribute technically part of feature policy, the allow attribute on an <iframe> specifies which web features the document in the frame should be allowed to access http public
key pinning (hpkp) hpkp is used by servers to instruct a client to associate a specific public
key with the server going forward in order to decrease the likelihood of man-in-the-middle attacks http strict transport security (hsts) hsts is used by servers to let them protect themselves from protocol downgrade and cookie hijack attacks by letting sites tell clients that they can only us...
...for example, in firefox 73, the user permission requests were revised so that when an <iframe> uses the allow
keyword to delegate permission to the embeded document, the browser asks the user to grant the parent document permission to use the resource, and that permission is then shared with the embedded content that requested the resource to begin with.

Using custom elements - Web Components
one of the
key features of the web components standard is the ability to create custom elements that encapsulate your functionality on an html page, rather than having to make do with a long, nested batch of elements that together provide a custom page feature.
...<custom-square l="100" c="red"></custom-square> the class constructor is really simple — here we attach a shadow dom to the element, then attach empty <div> and <style> elements to the shadow root: const shadow = this.attachshadow({mode: 'open'}); const div = document.createelement('div'); const style = document.createelement('style'); shadow.appendchild(style); shadow.appendchild(div); the
key function in this example is updatestyle() — this takes an element, gets its shadow root, finds its <style> element, and adds width, height, and background-color to the style.

Array.prototype.lastIndexOf() - JavaScript
math.min(n, len - 1) : len - math.abs(n); k >= 0; k--) { if (k in t && t[k] === searchelement) { return k; } } return -1; }; } again, note that this implementation aims for absolute compatibility with lastindexof in firefox and the spidermon
key javascript engine, including in several cases which are arguably edge cases.
Array.prototype.map() - JavaScript
let kvarray = [{

JSON - JavaScript
in engines that haven't implemented the proposal, u+2028 line separator and u+2029 paragraph separator are allowed in string literals and property
keys in json; but their use in these features in javascript string literals is a syntaxerror.
Map.prototype[@@iterator]() - JavaScript

key, it inherits error.prototype.message.
ReferenceError - JavaScript
although ecma-262 specifies that referenceerror should provide its own message property, in spidermon

Reflect.construct() - JavaScript
when using object.create() and function.prototype.apply(), the new.target operator will point to undefined within the function used as the constructor, since the new
keyword is not being used to create the object.
RegExp.prototype.sticky - JavaScript
examples using a regular expression with the sticky flag var str = '#foo#'; var regex = /foo/y; regex.lastindex = 1; regex.test(str); // true regex.lastindex = 5; regex.test(str); // false (lastindex is taken into account with sticky flag) regex.lastindex; // 0 (reset after match failure) anchored sticky flag for several versions, firefox's spidermon
key engine had a bug with regard to the ^ assertion and the sticky flag which allowed expressions starting with the ^ assertion and using the sticky flag to match when they shouldn't.
Set.prototype.has() - JavaScript
examples using the has method var myset = new set(); myset.add('foo'); myset.has('foo'); // returns true myset.has('bar'); // returns false var set1 = new set(); var obj1 = {'
key1': 1}; set1.add(obj1); set1.has(obj1); // returns true set1.has({'
