title: Javascript: find array by name
body: <p>I have some js arrays and I want to find the arrays by name. for example:</p>
  
  <pre><code>arr1 = [1,2,3];
  arr2 = [3,4,5];
  </code></pre>
  
  <p>And access them like this:</p>
  
  <pre><code>var intNum = 2;
  var arrName = 'arr' + intNum;
  
  arrName[0]; // equals 3
  </code></pre>
  
  <p>Is this possible?</p>
  
  <p>Thanks,
  Kevin</p>
