title: javascript push to array named as another array position
body: <p>If I have an array of strings like <code>stringsArray = [&quot;arrOne&quot;,&quot;arrTwo&quot;,&quot;arrThree&quot;]</code> and a list of arrays like <code>var arrOne = [], arrTwo = [], arrThree = []</code> is it possible to do something like:</p>
  <pre><code>stringsArray = [&quot;arrOne&quot;,&quot;arrTwo&quot;,&quot;arrThree&quot;]
  var arrOne = [], arrTwo = [], arrThree = []
  
  stringsArray[0].push(somestuff)
  </code></pre>
  <p>to basically push something into arrOne in this case</p>
