title: If conditional check in react jsx for empty values [es6]
body: <p>I have an array </p>
  
  <pre><code>const myArray = this.props.values.students;
  </code></pre>
  
  <p>How can I display none if the array is empty?</p>
  
  <p>This is what I'm currently using...</p>
  
  <pre><code>&lt;p&gt;{this.props.values.students ? myArray : 'None' }&lt;/p&gt;
  </code></pre>
  
  <p>It doesn't seem to render 'None' if the array is in-fact empty. How can I make this work?</p>
