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 }
