The Node.js [`Buffer`](https://nodejs.org/api/buffer.html) API predates the introduction of `ArrayBuffer` into the JavaScript language. Bun implements both.

Use the static `Buffer.from()` method to create a `Buffer` from an `ArrayBuffer`.

```ts
const arrBuffer = new ArrayBuffer(64);
const nodeBuffer = Buffer.from(arrBuffer);
```

***

To create a `Buffer` that only views a portion of the underlying buffer, pass the offset and length to `Buffer.from()`.

```ts
const arrBuffer = new ArrayBuffer(64);
const nodeBuffer = Buffer.from(arrBuffer, 0, 16); // view first 16 bytes
```
