Strange behavior when deleting object property after copying object
<pre><code>  myObj = {
    prop1: 'alpha',
    prop2: 'beta',
    priceUpdatedOn: new Date()
  };

  myObjQuery = myObj;
  delete myObjQuery.priceUpdatedOn;

console.log(myObj);
console.log(myObjQuery);
</code></pre>

<p>When I do that, the <code>priceUpdatedOn</code> gets deleted from <code>myObj</code> as well for some reason. Any idea why?</p>
