ECMAScript 2015 defines a TypedArray constructor that serves as the [[Prototype]] of all TypedArray constructors. This constructor is not directly exposed: there is no global% TypedArray% or TypedArray property. It is only directly accessible through Object.getPrototypeOf (Int8Array) and similar. All TypedArrays constructors inherit common properties from the% TypedArray% constructor function. Additionally, all typed array prototypes (TypedArray.prototype) have% TypedArray% .prototype as their [[Prototype]].
It is in the ES7 version when a new constructor is added, “forgotten” in the previous version.
