title: Convert JSON string to Javascript array
body: <p>I have an array of arrays which I have planted in the DOM, so that I can reuse it at a later stage to transfer to the server:</p>
  <pre><code>[[&quot;1&quot;,&quot;aaaaaa&quot;,&quot;1&quot;],[&quot;2&quot;,&quot;bbbbbbb&quot;,&quot;2&quot;],[&quot;3&quot;,&quot;ccccccc&quot;,&quot;3&quot;]]
  </code></pre>
  <p>If I would like to convert it back into a Javascript array, how would I go about doing this?</p>
