+name: Convert a Buffer to an ArrayBuffer
+---
+
+The Node.js [`Buffer`](https://nodejs.org/api/buffer.html) class provides a way to view and manipulate data in an underlying `ArrayBuffer`, which is available via the `buffer` property.
+
+```ts
+const nodeBuf = Buffer.alloc(64);
+const arrBuf = nodeBuf.buffer;
+```
