title: Cannot get length of a list
body: <p>Hay, i have the following list</p>
  
  <pre><code>var feedObjects = {
      0:[
          "url",
          "image"
      ],
      1:[
          "url",
          "image"
      ]
  }
  </code></pre>
  
  <p>However when i try doing feedObjects.length it always returns null, any ideas?</p>
