+name: Convert an ArrayBuffer to a Uint8Array
+---
+
+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 the constructor.
+
+```ts
+const arrBuffer = new ArrayBuffer(64);
+const nodeBuffer = Buffer.from(arrBuffer, 0, 16); // view first 16 bytes
+```
+

+
+See [Docs > API > Binary Data](/docs/api/binary-data#conversion) for complete documentation on manipulating binary data with Bun.
