title: Returning a value using Moment.js
body: <p>I'm using some of the date manipulation functions of <code>moment.js</code> such as add days.</p>
  
  <pre><code>import moment from 'moment';
  
  const addDays = (date, days) =&gt; {
      return moment(date).add(days, 'd');
  }
  </code></pre>
  
  <p>This seems to work but returns an object. How do I return a simple date value?</p>
