title: Convert javascript object containg keys/values without double quotes to pure JSON
body: <p>Given this object</p>
  
  <pre><code>Object { value=584, end_time="2013-11-03T07:00:00+0000"}
  </code></pre>
  
  <p>How do I convert to proper JSON?</p>
  
  <p><code>JSON.stringify</code> doesn't wrap double-quotes around keys/values without them in the object. I just get:</p>
  
  <pre><code>{"value":584,"end_time":"2013-11-03T07:00:00+0000"}
  </code></pre>
