What does from = mean inside a javascript function?
<p>I have the following call:</p>

<pre><code> $.extend($.fn.dataTableExt.oSort, {
        "datetime-uk-pre": function (a) {
            from = a.split(' ');
            var ukDatea = from[0].split('/');
            var ukTimea = from[1].split(':');
            return (ukDatea[2] + ukDatea[1] + ukDatea[0] + ukTimea[1] + ukTimea[0]) * 1;
        }
</code></pre>

<p>Can someone explain what the "from =" is doing here. I note that when I run 
JSHint then it tells me 'from' is not defined.</p>
