title: How to convert moment date to a string and remove the moment object
body: <p>I have a React Web App and a React Native Mobile App. When I pass a moment date object from my react web app to my backend, it gets converted to a string somehow and it works with my backend.</p>
  
  <p>When I do it with my react native mobile app, it passes the date as a moment object and it doesn't get converted to a string and it doesn't work.</p>
  
  <p>Is there a way to convert the moment object into a plain string like </p>
  
  <pre><code>"Tue May 05 2015 23:59:59 GMT+0800 (HKT)"
  </code></pre>
  
  <p>I tried toString() and toUTCString() and it doesn't work. Thanks.</p>
