is this jquery faster?
<p>I used to write this: </p>

<pre><code>$('#MyDiv .TheClass').eq(TheIndex).removeClass('ClassA');
$('#MyDiv .TheClass').eq(TheIndex).removeClass('ClassB');
$('#MyDiv .TheClass').eq(TheIndex).addClass('ClassC');

$('#MyDiv .TheClass').eq(TheIndex).children().each(function () {
 //do something here
});
</code></pre>

<p>and now I'm writing this:</p>

<pre><code>$('#MyDiv .TheClass').eq(TheIndex)
  .removeClass('ClassA ClassB')
  .addClass('ClassC')
  .children().each(function () { 
      // do something here
  });
</code></pre>

<p>Is the latter going to run faster than the former? Just curious. </p>
