title: javascript/jQuery Array concatenation?
body: <p>I have some simple jQuery code:</p>
  
  <pre><code>var response = Array()
  $('.task-list').each(function() {
    response.concat(response,$('#' + this.id).sortable('toArray'));
  }
  );
  console.log(response);
  </code></pre>
  
  <p>The problem I'm having is that I think I'm using concat improperly- the result is an empty array. When I use array push, it works correctly.</p>
