title: Javascript: Get first property of an object
body: <p>I am receiving back a response in the form of an object from Facebook API when I run a function that creates a Page Tab.</p>
  
  <p>Function I run: </p>
  
  <pre><code>   FB.ui({
        method: 'pagetab',
        redirect_uri: 'http://www.google.com'
      }, function(response){
          console.log(response.tabs_added)
      });
  </code></pre>
  
  <p>After <code>console.log(response.tabs_added)</code> this is what comes back:</p>
  
  <p><code>Object {491585370876358: true}</code></p>
  
  <p>The <code>491585370876358</code> is the ID of a page. How can I isolate this value?</p>
  
  <p>I imagine it would be console.log(response.tabs_added /<em>.something here</em>/);</p>
