TypedArray

A TypedArray object describes an array-like view of an underlying binary data buffer. There is no global property named TypedArray, nor is there a directly visible TypedArray constructor. Instead, there are a number of different global properties, whose values are typed array constructors for specific element types, listed below. On the following pages you will find common properties and methods that can be used with any typed array containing elements of any type.

The TypedArray constructor (often referred to as %TypedArray% to indicate its “intrinsicness”, since it does not correspond to any global exposed to a JavaScript program) serves as the common superclass of all TypedArray subclasses. Think about %TypedArray% as an “abstract class” providing a common interface of utility methods for all typed array subclasses. This constructor is not directly exposed: there is no global TypedArray property. It is only accessible through Object.getPrototypeOf(Int8Array) and similar.
