title: Returning nested arrays from multi-dimensional array
body: <p>Say I have the following 2x2 array:</p>
  
  <pre><code>var aTest = [
      ['test00','test01'],
      ['test10','test11']
  ]
  </code></pre>
  
  <p>I can return all of the nested arrays from the first (zero-eth), parent array. i.e.: aTest[0] returns</p>
  
  <pre><code>['test00', 'test01']
  </code></pre>
  
  <p>However, I can't do the same thing for the nested array without looping. i.e. I would like to do: aTest[][0]:</p>
  
  <pre><code>[['test00'],['test10']]
  </code></pre>
  
  <p>Am I mistaken? Is there no way to achieve this without loops:</p>
  
  <pre><code>var aTemp = new Array();
  for ( var i = 0; i &lt; aTest.length; i++ ) {
      aTemp[i] = new Array();
      aTemp[i][0] = aTest[i][0];
  };
  </code></pre>
