jQuery .each() this and element
<p>Inside a .each() callback, is there any difference between <code>this</code> and the second argument of the callback function?</p>

<p>For example, in the following code:</p>

<pre><code>$("example").each( function(index, element) {
    // body
});
</code></pre>

<p>is there any difference between <code>this</code> and <code>element</code>? Is the second argument just provided so you can choose a name?</p>
