title: How to go from Blob to ArrayBuffer
body: <p>I was studying Blobs, and I noticed that when you have an ArrayBuffer, you can easily convert this to a Blob as follows:</p>
  
  <pre><code>var dataView = new DataView(arrayBuffer);
  var blob = new Blob([dataView], { type: mimeString });
  </code></pre>
  
  <p>The question I have now is, is it possible to go from a Blob to an ArrayBuffer?</p>
