title: ng-repeat dynamic array name
body: <p>Is it possible to achieve dynamic array name, something like <code>friends+$index</code>. For example:</p>
  
  <pre><code>ng-repeat="friend in {{'friends'+$index}}"
  </code></pre>
  
  <p>The aim is to loop through different arrays: friends1 &amp; friends2.
  I tried everything, any combination, but without success. I also never came across to appropriate answers.</p>
  
  <p>Thanks in advance.</p>
