ArrayBuffer.prototype

The ArrayBuffer.prototype property represents the prototype for the ArrayBuffer object.

Description

ArrayBuffer instances inherit from ArrayBuffer.prototype. As with all constructors, you can change the constructor's prototype object to make changes to all ArrayBuffer instances.

Properties

ArrayBuffer.prototype.constructor

Specifies the function that creates an object's prototype. The initial value is the standard built-in ArrayBuffer constructor.

ArrayBuffer.prototype.byteLength Read only

The size, in bytes, of the array. This is established when the array is constructed and cannot be changed. Read only.

Methods

ArrayBuffer.prototype.slice()

Returns a new ArrayBuffer whose contents are a copy of this ArrayBuffer's bytes from begin, inclusive, up to end, exclusive. If either begin or end is negative, it refers to an index from the end of the array, as opposed to from the beginning.
