title: Looping Through Array with ngFor Using Next Button
body: <p>Somewhat new to Ionic 3 - I'm looking to loop through an array when I use ngFor. I've used the slice method to display one item from the array at a time. I'm looking to display the next item in the array when I click the "Next" button". </p>
  
  <pre><code>&lt;div *ngFor="let reference of content | slice:0:1;"&gt;
  &lt;div&gt; {{reference.item}} &lt;/div&gt;
  &lt;div&gt; {{reference.image}} &lt;/div&gt;
  &lt;div&gt; {{reference.field2}} &lt;/div&gt;
  
  &lt;button ion button&gt; Next &lt;/button&gt;
  </code></pre>
  
  <p>Not sure if ngFor is the best approach or if there is a better alternative. Thank you!</p>
