The [`Blob`](https://developer.mozilla.org/en-US/docs/Web/API/Blob) class provides several methods for consuming its contents in different formats. Read the contents into an `ArrayBuffer` with `.arrayBuffer()`, then create a `DataView` from the buffer.

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