Blob.arrayBuffer()

The arrayBuffer() method of the Blob interface returns a Promise that resolves with the contents of the blob as binary data contained in an ArrayBuffer.

Returns: A promise that resolves with an ArrayBuffer that contains the blob’s data in binary form.

Exceptions: While this method doesn’t throw exceptions, it may reject the promise. This can happen, for example, if the reader used to fetch the blob’s data throws an exception. Any exceptions thrown while getting the data will be converted into rejections.
