Minimal interface that an object must implement to be a valid context argument ( for interop between mismatching EVT versions )

A controller object that allows you to abort one or more DOM requests as and when desired.

A signal object that allows you to communicate with a DOM request (such as a Fetch) and abort it if required via an AbortController object.

A node able to provide real-time frequency and time-domain analysis information. It is an AudioNode that passes the audio stream unchanged from the input to the output, but allows you to take the generated data, process it, and create audio visualizations.

The ANGLE_instanced_arrays extension is part of the WebGL API and allows to draw the same object, or groups of similar objects multiple times, if they share the same vertex data, primitive count and type.

Events providing information related to animations.

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.

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.

An AudioScheduledSourceNode which represents an audio source consisting of in-memory audio data, stored in an AudioBuffer. It's especially useful for playing back audio which has particularly stringent timing accuracy requirements, such as for sounds that must match a specific rhythm and can be kept in memory rather than being played from disk or the network.

An audio-processing graph built from audio modules linked together, each represented by an AudioNode.

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 number of channels in the input must be between 0 and the maxChannelCount value or an exception is raised.

The position and orientation of the unique person listening to the audio scene, and is used in audio spatialization. All PannerNodes spatialize in relation to the AudioListener stored in the BaseAudioContext.listener attribute.

A generic interface for representing an audio processing module. Examples include:

The Web Audio API's AudioParam interface represents an audio-related parameter, usually a parameter of an AudioNode (such as GainNode.gain).

The Web Audio API events that occur when a ScriptProcessorNode input buffer is ready to be processed.

A single audio track from one of the HTML media elements, or .

Used to represent a list of the audio tracks contained within a given HTML media element, with each track represented by a separate AudioTrack object in the list.

The beforeunload event is fired when the window, the document and its resources are about to be unloaded.

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 file-like object of immutable, raw data. Blobs 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.

This Streams API interface provides a built-in byte length queuing strategy that can be used when constructing streams.

Provides a storage mechanism for Request / Response object pairs that are cached, for example as part of the ServiceWorker life cycle. Note that the Cache interface is exposed to windowed scopes as well as workers. You don't have to use it in conjunction with service workers, even though it is defined in the service worker spec.

The storage for Cache objects.

An opaque object describing a gradient. It is returned by the methods CanvasRenderingContext2D.createLinearGradient() or CanvasRenderingContext2D.createRadialGradient().

An opaque object describing a pattern, based on an image, a canvas, or a video, created by the CanvasRenderingContext2D.createPattern() method.

The CanvasRenderingContext2D interface, part of the Canvas API, provides the 2D rendering context for the drawing surface of a element. It is used for drawing shapes, text, images, and other objects.

A CDATA section that can be used within XML to include extended portions of unescaped text. The symbols < and & don’t need escaping as they normally do when inside a CDATA section.

The ChannelMergerNode interface, often used in conjunction with its opposite, ChannelSplitterNode, reunites different mono inputs into a single output. Each input is used to fill a channel of the output. This is useful for accessing each channels separately, e.g. for performing channel mixing where gain must be separately controlled on each channel.

The ChannelSplitterNode interface, often used in conjunction with its opposite, ChannelMergerNode, separates the different channels of an audio source into a set of mono outputs. This is useful for accessing each channel separately, e.g. for performing channel mixing where gain must be separately controlled on each channel.

The CharacterData abstract interface represents a Node object that contains characters. This is an abstract interface, meaning there aren't any object of type CharacterData: it is implemented by other interfaces, like Text, Comment, or ProcessingInstruction which aren't abstract.

Events providing information related to modification of the clipboard, that is cut, copy, and paste events.

A CloseEvent is sent to clients using WebSockets when the connection is closed. This is delivered to the listener indicated by the WebSocket object's onclose attribute.

Textual notations within markup; although it is generally not visually shown, such comments are available to be read in the source view.

The DOM CompositionEvent represents events that occur due to the user indirectly entering text.

Provides access to the browser's debugging console (e.g. the Web Console in Firefox). The specifics of how it works varies from browser to browser, but there is a de facto set of features that are typically provided.
