looping through javascript array each time starting at new index
<p>i have a javascript array like this:</p>

<pre><code> array = [
  {"Command": "SetDuration","QuestionId": "2","NewDuration": "1"},
  {"Command": "SetDuration","QuestionId": "2","NewDuration": "1"},
  {"Command": "SetDuration","QuestionId": "7","NewDuration": "7"},
  {"Command": "SetDuration","QuestionId": "6","NewDuration": "7"}
 ]
</code></pre>

<p>my task is loop through it 1 time in a minute, starting at incremented index each time, so that after 3 minutes i would start from array[4]
How to accomplish this?
Thanks!</p>
