title: Map returns multiple array elements for each element It iterates
body: <p>instead of pushing into an empty array, I wanted to try to combine it into my variable declaration.</p>
  
  <pre><code>var blah = [1,2,3].map(function(x){ 
     return (x+'a'),(x+'b'),(x+'c')
  });
  
  //outcome =&gt; ['1a', '1b', '1c', '2a', '2b', '2c', '3a', '3b', '3c']
  </code></pre>
