Interactive exampleOpen the canonical MDN source to run this embedded demo.
// Create an ArrayBuffer
const buffer = new ArrayBuffer(123);
// Create a view
const view = new DataView(buffer);
console.log(view.buffer.byteLength);
// Expected output: 123
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
const buffer = new ArrayBuffer(8);
const dataview = new DataView(buffer);
dataview.buffer; // ArrayBuffer { byteLength: 8 }
