The buffer accessor property represents the ArrayBuffer referenced by a TypedArray at construction time.

Syntax

typedArray.buffer

Description

The buffer property is an accessor property whose set accessor function is undefined, meaning that you can only read this property. The value is established when the TypedArray is constructed and cannot be changed. TypedArray is one of the TypedArray objects.

Examples

Using the buffer property

var buffer = new ArrayBuffer(8);
var uint16 = new Uint16Array(buffer);
uint16.buffer; // ArrayBuffer { byteLength: 8 }
