javascript/jQuery Array concatenation?
<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>
