Convert a Blob to a Uint8Array with Bun

The Blob class provides a number of methods for consuming its contents in different formats. This snippets reads the contents to an ArrayBuffer, then creates a Uint8Array from the buffer.

const blob = new Blob(["hello world"]);
const arr = new Uint8Array(await blob.arrayBuffer());
