The element there will always be the same as this.

jsFiddle.

Except wrapping it in $() will make it a jQuery object, and won't be equal to the other one, even if you wrap the other with a jQuery object.

There should never be a reason why you need to pare this to element in that context.

$('div').each(function(index, element) {
     //element != $(this)
     //element == this
});

$(this) is this wrapped by a jquery object. So while this won't equal $(this), you can still manipulate it to your heart's content

Here's something to look at : http://jsfiddle/jomanlk/ZqXPn/
