--- name: Convert an ArrayBuffer to an array of numbers --- To retrieve the contents of an `ArrayBuffer` as an array of numbers, create a [`Uint8Array`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array) over of the buffer. and use the [`Array.from()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/from) method to convert it to an array. ```ts 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.) ```ts const buf = new ArrayBuffer(64); const uintArr = new Uint8Array(buf); const regularArr = Array.from(uintArr); // number[] ``` --- See [Docs > API > Binary Data](/docs/api/binary-data#conversion) for complete documentation on manipulating binary data with Bun.
