What is ArrayBuffer
An ArrayBuffer object is used to represent a generic, fixed-length raw binary data buffer. You can create it as below,
javascript
let buffer = new ArrayBuffer(16); // create a buffer of length 16
alert(buffer.byteLength); // 16
To manipulate an ArrayBuffer, we need to use a “view” object.
javascript
//Create a DataView referring to the buffer
let view = new DataView(buffer);
