To retrieve the contents of an ArrayBuffer as an array of numbers, create a Uint8Array over of the buffer. and use the Array.from() method to convert it to an array. 
const buf = new ArrayBuffer(64); const arr = new Uint8Array(buf); arr.length; // 64 arr[0]; // 0 (instantiated with all zeros)
The Uint8Array class supports array indexing and iteration. However if you wish to convert the instance to a regular Array, use Array.from(). (This will likely be slower than using the Uint8Array directly.) 
const buf = new ArrayBuffer(64); const uintArr = new Uint8Array(buf); const regularArr = Array.from(uintArr); // number[]
