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.

This IndexedDB API interface represents a cursor for traversing or iterating over multiple records in a database.

This IndexedDB API interface represents a cursor for traversing or iterating over multiple records in a database. It is the same as the IDBCursor, except that it includes the value property.

This IndexedDB API interface provides a connection to a database; you can use an IDBDatabase object to open a transaction on your database then create, manipulate, and delete objects (data) in that database. The interface provides the only way to get and manage versions of the database.

In the following code snippet, we make a request to open a database, and include handlers for the success and error cases. For a full working example, see our To-do Notifications app (view example live.)

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.

A key range can be 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:

This example shows a variety of different uses of object stores, from updating the data structure with IDBObjectStore.createIndex inside an onupgradeneeded function, to adding a new item to our object store with IDBObjectStore.add. For a full working example, see our To-do Notifications app (view example live.)

Also inherits methods from its parents IDBRequest and EventTarget.

The request object does not initially contain any information about the result of the operation, but once information becomes available, an event is fired on the request, and the information becomes available through the properties of the IDBRequest instance.

This IndexedDB API interface indicates that the version of the database has changed, as the result of an IDBOpenDBRequest.onupgradeneeded event handler function.

A type of AudioNode which operates as an audio source whose media is received from a MediaStream obtained using the WebRTC or Media Capture and Streams APIs.

Events that occurs in relation to a MediaStream. Two events of this type can be thrown: addstream and removestream.

A single media track within a stream; typically, these are audio or video tracks, but other track types may exist as well.

Events which indicate that a MediaStream has had tracks added to or removed from the stream through calls to Media Stream API methods. These events are sent to the stream when these changes occur.

This Channel Messaging API interface allows us to create a new message channel and send data through it via its two MessagePort properties.

A message received by a target object.

This Channel Messaging API interface represents one of the two ports of a MessageChannel, allowing messages to be sent from one port and listening out for them arriving at the other.

Node is an interface from which a number of DOM API object types inherit. It allows those types to be treated similarly; for example, inheriting the same set of methods, or being tested in the same way.

An object used to filter the nodes in a NodeIterator or TreeWalker. They don't know anything about the DOM or how to traverse nodes; they just know how to evaluate a single node against the provided filter.
