title: New JQuery.Deferred(); isn't a constructor
body: <p>I asked a question <a href="https://stackoverflow.com/questions/17737191/get-value-from-jquery-function"> here</a> yesterday, i got a good answer with this line of code <code>var def = new jQuery.Deferred();</code>  the code is working fine at jsfiddle.net, but my firebug says that <code>TypeError: jQuery.Deferred is not a constructor</code>, and with this code <code>var def = jQuery.Deferred();</code> it said <code>TypeError: jQuery.Deferred is not a function</code></p>
