title: A vanilla Array of Floats from an ArrayBuffer
body: <p>There are a number of questions and resources about getting <em>Typed</em> arrays from an <code>ArrayBuffer</code>. An example:  <a href="https://stackoverflow.com/questions/52391921/how-to-get-an-array-from-arraybuffer">How to get an array from ArrayBuffer?</a>. I need an actual <em>array</em></p>
  <p>I tried <code>Array.from(myArrayBuffer)</code> and get this:</p>
  <pre><code>//  buf is an ArrayBuffer(878468)
  Array.from(buf) //  Array(0)  length: 0
  </code></pre>
