title: React: export const + export default vs export default
body: <p>I've come across current component creation with "double" export. Can you please explain if there is a real use of it, or it's just author preference? </p>
  
  <pre><code>import React from 'react'
  import DuckImage from '../assets/Duck.jpg'
  import './HomeView.scss'
  
  export const HomeView = () =&gt; (
    &lt;div&gt;
      &lt;h4&gt;Welcome!&lt;/h4&gt;
      &lt;img
        alt='This is a duck, because Redux!'
        className='duck'
        src={DuckImage} /&gt;
    &lt;/div&gt;
  )
  
  export default HomeView
  </code></pre>
  
  <p>P.S: Current code is later bundled by webpack2.</p>
