This type represents a DOM element's attribute as an object.
This type represents a DOM element's attribute as an object. In most DOM methods, you will probably directly retrieve the attribute as a string (e.g., Element.getAttribute(), but certain functions (e.g., Element.getAttributeNode()) or means of iterating give Attr types.
The AudioBuffer interface represents a short audio asset residing in memory, created from an audio file using the AudioContext.decodeAudioData() method, or from raw data using AudioContext.createBuffer().
The AudioBuffer interface represents a short audio asset residing in memory, created from an audio file using the AudioContext.decodeAudioData() method, or from raw data using AudioContext.createBuffer(). Once put into an AudioBuffer, the audio can then be played by being passed into an AudioBufferSourceNode.
Objects of these types are designed to hold small audio snippets, typically less than 45 s. For longer sounds, objects implementing the MediaElementAudioSourceNode are more suitable.
The buffer contains data in the following format: non-interleaved IEEE754 32-bit linear PCM with a nominal range between -1 and +1, that is, 32bits floating point buffer, with each samples between -1.0 and 1.0. If the AudioBuffer has multiple channels, they are stored in separate buffer.
AudioBufferSourceNode has no input and exactly one output.
AudioBufferSourceNode has no input and exactly one output. The number of channels in the output corresponds to the number of channels of the AudioBuffer that is set to the AudioBufferSourceNode.buffer property. If there is no buffer set—that is, if the attribute's value is NULL—the output contains one channel consisting of silence. An AudioBufferSourceNode can only be played once; that is, only one call to AudioBufferSourceNode.start() is allowed. If the sound needs to be played again, another AudioBufferSourceNode has to be created. Those nodes are cheap to create, and AudioBuffers can be reused across plays. It is often said that AudioBufferSourceNodes have to be used in a "fire and forget" fashion: once it has been started, all references to the node can be dropped, and it will be garbage-collected automatically.
Multiple calls to AudioBufferSourceNode.stop() are allowed. The most recent call replaces the previous one, granted the AudioBufferSourceNode has not already reached the end of the buffer.
The AudioContext interface represents an audio-processing graph built from audio modules linked together, each represented by an AudioNode.
The AudioContext interface represents an audio-processing graph built from audio modules linked together, each represented by an AudioNode. An audio context controls both the creation of the nodes it contains and the execution of the audio processing, or decoding. You need to create an AudioContext before you do anything else, as everything happens inside a context.
An AudioContext can be a target of events, therefore it implements the EventTarget interface.
The AudioDestinationNode interface represents the end destination of an audio graph in a given context — usually the speakers of your device.
The AudioDestinationNode interface represents the end destination of an audio graph in a given context — usually the speakers of your device. It can also be the node that will "record" the audio data when used with an OfflineAudioContext.
AudioDestinationNode has no output (as it is the output, no more AudioNode can be linked after it in the audio graph) and one input. The amount of channels in the input must be between 0 and the maxChannelCount value or an exception is raised.
The AudioDestinationNode of a given AudioContext can be retrieved using the AudioContext.destination property.
The AudioListener interface represents the position and orientation of the unique person listening to the audio scene, and is used in audio spatialisation.
The AudioListener interface represents the position and orientation of the unique person listening to the audio scene, and is used in audio spatialisation. All PannerNodes spatialise in relation to the AudioListener stored in the AudioContext.listener attribute.
It is important to note that there is only one listener per context and that it isn't an AudioNode.
The AudioNode interface is a generic interface for representing an audio processing module like an audio source (e.g.
The AudioNode interface is a generic interface for representing an audio processing module like an audio source (e.g. an HTML <audio> or <video> element, an OscillatorNode, etc.), the audio destination, intermediate processing module (e.g. a filter like BiquadFilterNode or ConvolverNode), or volume control (like GainNode).
An AudioNode has inputs and outputs, each with a given amount of channels. An AudioNode with zero inputs and one or multiple outputs is called a source node. The exact processing done varies from one AudioNode to another but, in general, a node reads its inputs, does some audio-related processing, and generates new values for its outputs, or simply lets the audio pass through (for example in the AnalyserNode, where the result of the processing is accessed separately).
Different nodes can be linked together to build a processing graph. Such a graph is contained in an AudioContext. Each AudioNode participates in exactly one such context. In general, processing nodes inherit the properties and methods of AudioNode, but also define their own functionality on top. See the individual node pages for more details, as listed on the Web Audio API homepage.
The AudioParam interface represents an audio-related parameter, usually a parameter of an AudioNode (such as GainNode.gain).
The AudioParam interface represents an audio-related parameter, usually a parameter of an AudioNode (such as GainNode.gain). An AudioParam can be set to a specific value or a change in value, and can be scheduled to happen at a specific time and following a specific pattern.
There are two kinds of AudioParam, a-rate and k-rate parameters:
Each AudioNode defines which of its parameters are a-rate or k-rate in the spec.
Each AudioParam has a list of events, initially empty, that define when and how values change. When this list is not empty, changes using the AudioParam.value attributes are ignored. This list of events allows us to schedule changes that have to happen at very precise times, using arbitrary timelime-based automation curves. The time used is the one defined in AudioContext.currentTime.
The BiquadFilterNode interface represents a simple low-order filter, and is created using the AudioContext.createBiquadFilter() method.
The BiquadFilterNode interface represents a simple low-order filter, and is created using the AudioContext.createBiquadFilter() method. It is an AudioNode that can represent different kinds of filters, tone control devices, and graphic equalizers. A BiquadFilterNode always has exactly one input and one output.
A Blob object represents a file-like object of immutable, raw data; they can be read as text or binary data, or converted into a ReadableStream so its methods can be used for processing the data.
A Blob object represents a file-like object of immutable, raw data; they can be read as text or binary data, or converted into a ReadableStream so its methods can be used for processing the data. Blobs can represent data that isn't necessarily in a JavaScript-native format. The File interface is based on Blob, inheriting blob functionality and expanding it to support files on the user's system.
To construct a Blob from other non-blob objects and data, use the Blob() constructor. To create a blob that contains a subset of another blob's data, use the slice() method. To obtain a Blob object for a file on the user's file system, see the File documentation.
The APIs accepting Blob objects are also listed in the File documentation.

¶6.1 Headers Class of whatwg spec
The Headers interface of the Fetch API allows you to perform various actions on HTTP request and response headers. These actions include retrieving, setting, adding to, and removing. A Headers object has an associated header list, which is initially empty and consists of zero or more name and value pairs. You can add to this using methods like append() (see Examples.) In all methods of this interface, header names are matched by case-insensitive byte sequence.
For security reasons, some headers can only be controller by the user agent. These headers include the forbidden header names and forbidden response header names.
A Headers object also has an associated guard, which takes a value of immutable, request, request-no-cors, response, or none. This affects whether the set(), delete(), and append() methods will mutate the header. For more information see Guard.
You can retrieve a Headers object via the Request.headers and Response.headers properties, and create a new Headers object using the Headers.Headers() constructor.

The IDBCursor interface of the IndexedDB API represents a cursor for traversing or iterating over multiple records in a database.
The IDBCursor interface of the IndexedDB API represents a cursor for traversing or iterating over multiple records in a database.
The cursor has a source that indicates which index or object store it is iterating. It has a position within the range, and moves in a direction that is increasing or decreasing in the order of record keys. The cursor enables an application to asynchronously process all the records in the cursor's range.

The IDBDatabase interface of the IndexedDB API provides asynchronous access to a connection to a database.
The IDBDatabase interface of the IndexedDB API provides asynchronous access to a connection to a database. Use it to create, manipulate, and delete objects in that database. The interface also provides the only way to get a transaction and manage versions on that database.
Everything you do in IndexedDB always happens in the context of a transaction, representing interactions with data in the database. All objects in IndexedDB—including object stores, indexes, and cursors—are tied to a particular transaction. Thus, you cannot execute commands, access data, or open anything outside of a transaction.
Type of .target.result
The IDBFactory interface of the IndexedDB API lets applications asynchronously access the indexed databases.
The IDBFactory interface of the IndexedDB API lets applications asynchronously access the indexed databases. The object that implements the interface is window.indexedDB. You open — that is, create and access — and delete a database with the object and not directly with IDBFactory. see IDBFactory on MDN
official documentation IDBFactory in w3c spec
The IDBIndex interface of the IndexedDB API provides asynchronous access to an index in a database.
The IDBIndex interface of the IndexedDB API provides asynchronous access to an index in a database. An index is a kind of object store for looking up records in another object store, called the referenced object store. You use this interface to retrieve data.
You can retrieve records in an object store through their keys or by using an index (cursors provide a third way: see IDBCursor). An index lets you look up records in an object store using properties of the values in the object stores records.
The index is a persistent key-value storage where the value part of its records is the key part of a record in the referenced object store. The records in an index are automatically populated whenever records in the referenced object store are inserted, updated, or deleted. Each record in an index can point to only one record in its referenced object store, but several indexes can reference the same object store. When the object store changes, all indexes that refers to the object store are automatically updated.
A valid key path can include one of the following: an empty string, a JavaScript identifier, or multiple JavaScript identifiers separated by periods or an array containing any of those.
A valid key path can include one of the following: an empty string, a JavaScript identifier, or multiple JavaScript identifiers separated by periods or an array containing any of those. It cannot include spaces.

The IDBKeyRange interface of the IndexedDB API represents a continuous interval over some data type that is used for keys.
The IDBKeyRange interface of the IndexedDB API represents a continuous interval over some data type that is used for keys. Records can be retrieved from object stores and indexes using keys or a range of keys. You can limit the range using lower and upper bounds. For example, you can iterate over all values of a key between x and y.
A key range can have a single value or a range with upper and lower bounds or endpoints. If the key range has both upper and lower bounds, then it is bounded; if it has no bounds, it is unbounded. A bounded key range can either be open (the endpoints are excluded) or closed (the endpoints are included). To retrieve all keys within a certain range, you can use the following code constructs:
The IDBObjectStore interface of the IndexedDB API represents an object store in a database.
The IDBObjectStore interface of the IndexedDB API represents an object store in a database. Records within an object store are sorted according to their keys. This sorting enables fast insertion, look-up, and ordered retrieval.

The OfflineAudioContext interface is an AudioContext interface representing an audio-processing graph built from linked together AudioNodes. In contrast with a standard AudioContext, an OfflineAudioContext doesn't render the audio to the device hardware; instead, it generates it, as fast as it can, and outputs the result to an AudioBuffer.
It is important to note that, whereas you can create a new AudioContext using the new AudioContext() constructor with no arguments, the new OfflineAudioContext() constructor requires three arguments:
new OfflineAudioContext(numOfChannels, length, sampleRate)This works in exactly the same way as when you create a new AudioBuffer with the AudioContext.createBuffer method. For more detail, read Audio buffers: frames, samples and channels from our Basic concepts guide.
The OffscreenCanvas interface provides a canvas that can be rendered off screen.

The OscillatorNode interface represents a periodic waveform, like a sine wave.
The OscillatorNode interface represents a periodic waveform, like a sine wave. It is an AudioNode audio-processing module that causes a given frequency of sine wave to be created — in effect, a constant tone.
An OscillatorNode is created using the AudioContext.createOscillator method. It always has exactly one output and no inputs, both with the same amount of channels. Its basic property defaults (see AudioNode for definitions) are:
The PageTransitionEvent is fired when a document is being loaded or unloaded.
The PageTransitionEvent is fired when a document is being loaded or unloaded.
This interface also inherits properties from its parent, Event.
The Page Visibility API lets you know when a webpage is visible or in focus.
The Page Visibility API lets you know when a webpage is visible or in focus. With tabbed browsing, there is a reasonable chance that any given webpage is in the background and thus not visible to the user. When the user minimizes the webpage or moves to another tab, the API sends a visibilitychange event regarding the visibility of the page. You can detect the event and perform some actions or behave differently. For example, if your web app is playing a video, it would pause the moment the user looks at another browser, and plays again when the user returns to the tab. The user does not lose their place in the video and can continue watching.

The PannerNode interface represents the position and behavior of an audio source signal in space.
The PannerNode interface represents the position and behavior of an audio source signal in space. It is an AudioNode audio-processing module describing its position with right-hand Cartesian coordinates, its movement using a velocity vector and its directionality using a directionality cone.
A PannerNode always has exactly one input and one output: the input can be mono or stereo but the output is always stereo (2 channels) — you need stereo sound for panning effects!
The PannerNode brings a spatial position and velocity and a directionality for a given signal.
The ParentNode interface allows to traverse from an element to its children.

Most of today's web content assumes the user's pointing device will be a mouse.
Most of today's web content assumes the user's pointing device will be a mouse. However, since many devices support other types of pointing input devices, such as pen/stylus and touch surfaces, extensions to the existing pointing device event models are needed and pointer events address that need.
Pointer events are DOM events that are fired for a pointing device. They are designed to create a single DOM event model to handle pointing input devices such as a mouse, pen/stylus or touch (such as one or more fingers). The pointer is a hardware-agnostic device that can target a specific set of screen coordinates. Having a single event model for pointers can simplify creating Web sites and applications and provide a good user experience regardless of the user's hardware. However, for scenarios when device-specific handling is desired, pointer events defines a property to inspect the device type which produced the event.
The events needed to handle generic pointer input are analogous to mouse events (mousedown/pointerdown, mousemove/pointermove, etc.). Consequently, pointer event types are intentionally similar to mouse event types. Additionally, a pointer event contains the usual properties present in mouse events (client coordinates, target element, button states, etc.) in addition to new properties for other forms of input: pressure, contact geometry, tilt, etc. In fact, the PointerEvent interface inherits all of the MouseEvent's properties thus facilitating migrating content from mouse events to pointer events.
The Position interface represents the position of the concerned device at a given time.

A Touch object represents a single point of contact between the user and a touch-sensitive interface device (which may be, for example, a touchscreen or a trackpad).
A Touch object represents a single point of contact between the user and a touch-sensitive interface device (which may be, for example, a touchscreen or a trackpad).
Note: Many of these values are hardware-dependent; for example, if the device doesn't have a way to detect the amount of pressure placed on the surface, the force value will always be 1.0. This may also be the case for radiusX and radiusY; if the hardware reports only a single point, these values will be 1.
A TouchEvent represents an event sent when the state of contacts with a touch-sensitive surface changes.
A TouchEvent represents an event sent when the state of contacts with a touch-sensitive surface changes. This surface can be a touch screen or trackpad, for example. The event can describe one or more points of contact with the screen and includes support for detecting movement, addition and removal of contact points, and so forth.
Touches are represented by the Touch object; each touch is described by a position, size and shape, amount of pressure, and target element. Lists of touches are represented by TouchList objects.
A TouchList represents a list of all of the points of contact with a touch surface; for example, if the user has three fingers on the screen (or trackpad), the corresponding TouchList would have one Touch object for each finger, for a total of three entries.

The Transferable interface represents an object that can be transfered between different execution contexts, like the main thread and Web workers.
The Transferable interface represents an object that can be transfered between different execution contexts, like the main thread and Web workers.
This is an abstract interface and there isn't any object of this type. It also doesn't define any method or property: it is merely a tag indicating objects that can be used in specific conditions, like to be transfered to a Worker using the Worker.postMessage() method.
The TransitionEvent interface represents events providing information related to transitions.

The DOM WheelEvent represents events that occur due to the user moving a mouse wheel or similar input device.
The DOM WheelEvent represents events that occur due to the user moving a mouse wheel or similar input device.
The window object represents the window itself.
The window object represents the window itself. The document property of a window points to the DOM document loaded in that window. A window for a given document can be obtained using the document.defaultView property.
In a tabbed browser, such as Firefox, each tab contains its own window object (and if you're writing an extension, the browser window itself is a separate window too - see Working with windows in chrome code for more information). That is, the window object is not shared between tabs in the same window. Some methods, namely window.resizeTo and window.resizeBy apply to the whole window and not to the specific tab the window object belongs to. Generally, anything that can't reasonably pertain to a tab pertains to the window instead.
The WindowClient interface of the ServiceWorker API represents the scope of a service worker client that is a document in a browser context, controlled by an active worker.
The WindowClient interface of the ServiceWorker API represents the scope of a service worker client that is a document in a browser context, controlled by an active worker. The service worker client independently selects and uses a service worker for its own loading and sub-resources.
The WindowOrWorkerGlobalScope mixin describes several features common to the Window and WorkerGlobalScope interfaces.
The WindowOrWorkerGlobalScope mixin describes several features common to the Window and WorkerGlobalScope interfaces.
Note: WindowOrWorkerGlobalScope is a mixin and not an interface; you can't actually create an object of type WindowOrWorkerGlobalScope.
The Worker interface represents a background task that can be easily created and can send messages back to their creators.
The Worker interface represents a background task that can be easily created and can send messages back to their creators. Creating a worker is as simple as calling the Worker() constructor, specifying a script to be run in the worker thread.
Of note is the fact that workers may in turn spawn new workers as long as those workers are hosted within the same origin as the parent page. In addition, workers may use XMLHttpRequest for network I/O, with the exception that the responseXML and channel attributes on XMLHttpRequest always return null.
The WorkerGlobalScope interface of the Web Workers API is an interface representing the scope of any worker.
The WorkerGlobalScope interface of the Web Workers API is an interface representing the scope of any worker. Workers have no browsing context; this scope contains the information usually conveyed by Window objects — in this case event handlers, the console or the associated WorkerNavigator object. Each WorkerGlobalScope has its own event loop.
This interface is usually specialized by each worker type: DedicatedWorkerGlobalScope for dedicated workers, SharedWorkerGlobalScope for shared workers, and ServiceWorkerGlobalScope for ServiceWorker. The self property returns the specialized scope for each context.
The WorkerLocation interface defines the absolute location of the script executed by the Worker.
The WorkerLocation interface defines the absolute location of the script executed by the Worker. Such an object is initialized for each worker and is available via the WorkerGlobalScope.location property obtained by calling window.self.location.
The WorkerNavigator interface represents a subset of the Navigator interface allowed to be accessed from a Worker.
The WorkerNavigator interface represents a subset of the Navigator interface allowed to be accessed from a Worker. Such an object is initialized for each worker and is available via the WorkerGlobalScope.navigator property obtained by calling window.self.navigator

XMLHttpRequest is a JavaScript object that was designed by Microsoft and adopted by Mozilla, Apple, and Google.
XMLHttpRequest is a JavaScript object that was designed by Microsoft and adopted by Mozilla, Apple, and Google. It's now being standardized in the W3C. It provides an easy way to retrieve data from a URL without having to do a full page refresh. A Web page can update just a part of the page without disrupting what the user is doing. XMLHttpRequest is used heavily in AJAX programming.
Despite its name, XMLHttpRequest can be used to retrieve any type of data, not just XML, and it supports protocols other than HTTP (including file and ftp).
XMLHttpRequestEventTarget is the interface that describes the event handlers you can implement in an object that will handle events for an XMLHttpRequest.

(Since version 1.2.0) Removed. This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible. See https://developer.mozilla.org/en-US/docs/Web/API/IDBEnvironment

When dragging, there are several operations that may be performed.
When dragging, there are several operations that may be performed. The copy operation is used to indicate that the data being dragged will be copied from its present location to the drop location. The move operation is used to indicate that the data being dragged will be moved, and the link operation is used to indicate that some form of relationship or connection will be created between the source and drop locations.
You can specify which of the three operations are allowed for a drag source by setting the effectAllowed property
within a dragstart event listener.
Note that these values must be used exactly as defined below.

The KeyboardEvent.key attribute of an event must always contain one of these control key or character values (even if the value is 'Unidentified').
The KeyboardEvent.key attribute of an event must always contain one of these control key or character values (even if the value is 'Unidentified').
If the key represents one of the set of printable control characters which has a Unicode character entry, such as the tab key, the KeyboardEvent.key attribute must have the key value (e.g., 'Tab').
Implementations that are unable to identify a key must use the key value 'Unidentified'.
