Web/JavaScript/Reference/Global objects/DataView/buffer

The buffer accessor property represents the ArrayBuffer or SharedArrayBuffer referenced by the DataView at construction time.

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 DataView is constructed and cannot be changed.

Examples

Using the buffer property

var buffer = new ArrayBuffer(8);
var dataview = new DataView(buffer);
dataview.buffer; // ArrayBuffer { byteLength: 8 }
