title: How to display items in an array in order and once?
body: <p>If I have an array; </p>
  
  <pre><code>var array = [item1, item2, item3, item4, item5];
  </code></pre>
  
  <p>How would I return every item once in order?</p>
  
  <p>I tried the following but that returns the items randomly and it can repeat what it already displayed. But how do I get it so the items are not repeated? </p>
  
  <pre><code>var randomReturn = array[Math.floor(Math.random() * array.length)];
  </code></pre>
