title: Significance of ng-repeat-start vs ng-repeat
body: <p>I am trying to understand the significance of <code>ng-repeat-start</code> over <code>ng-repeat</code>. The angular documentation provides the following example for <code>ng-repeat-start</code></p>
  
  <pre><code>&lt;header ng-repeat-start="item in items"&gt;
    Header {{ item }}
  &lt;/header&gt;
  &lt;div class="body"&gt;
    Body {{ item }}
  &lt;/div&gt;
  &lt;footer ng-repeat-end&gt;
    Footer {{ item }}
  &lt;/footer&gt;
  </code></pre>
  
  <p>But the same can be achived using <code>ng-repeat</code>, </p>
  
  <pre><code>&lt;div ng-repeat="item in items"&gt;
    &lt;header&gt;
      Header {{ item }}
    &lt;/header&gt;
    &lt;div class="body"&gt;
      Body {{ item }}
    &lt;/div&gt;
    &lt;footer&gt;
      Footer {{ item }}
    &lt;/footer&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Can someone explain the significance of <code>ng-repeat-start</code>.? Thanks.</p>
