title: Use pop() with JavaScript Associative Arrays
body: <p>How can I do something like the following in JS? I would like to imitate <code>.pop()</code> on an object rather than an array.</p>
  
  <pre><code>var deck = { 
      'cardK' :'13',
      'cardQ' :'12',
      'cardAJ':'11'
  };
  
  var val = deck.pop();
  
  
  console.log("Key" + val.key ); 
  console.log("Value" + val.val ); 
  </code></pre>
  
  <p>It seems like it's not possible.</p>
