title: Need to access data in JSON.stringify object
body: <p>The background for this question is I'm trying to access the selected cell from addListener in google visualization calendar. I could print the selected cell using <code>JSON.stringify(chart.getSelection());</code>. It prints as <code>[{"date":1468195200000,"row":0}]</code>. </p>
  
  <p><strong>My problem</strong> is to access this date object. I tried to access it as </p>
  
  <pre><code>var obj=JSON.stringify(chart.getSelection());
          console.log('selected value '+obj.date);
  </code></pre>
  
  <p>But it displays as <code>Undefined</code>. When I print the <code>obj</code> it displays as [object, object]</p>
  
  <p>If you need more information please let me know. Any suggestion would be appreciated. </p>
