title: How to make InstanceOf work with object from Local Storage
body: <p>I have an object which is an instance of a class.  I then save it to local storage with <code>JSON.stringify</code> and then retrieve it with <code>JSON.Parse</code>.  However, after retrieving it, it is no longer an instance of the class.  How do I make it so that it is an instance of the class?</p>
  
  <p>In other words, I need <code>instanceOf</code> to work correctly after retrieving it.</p>
