  </code></pre>
  
  <p>I want to know how to index the last thing of this json object. I can't describe it any more but it might be the key.</p>
  
  <p>I want to basically index the last object in the object, so that would be the bit where it says <code>"872":{"header":"New Hat"</code> near the bottom</p>
  
  <p>So basically it's the biggest number I want to index. I already tried to index the last one with <code>[4]</code> as an index but it came up with undefined.</p>
