title: How to format date in react native without third party libraries
body: <p>I want to display date as a string in react native.<br/>
  And I am trying to use phone locale to format it according to that locale.</p>
  
  <pre><code>var dt = moment(this.state.dt).locale('en-us', localization).format('LL')
  </code></pre>
  
  <p>I can do this with moment but is there a way to do this with clean RN?</p>
