Which is faster: input[type="checkbox"] or :checkbox?
<p>So which should I use to select elements? I'm using checkbox as just an example, this question refers to all form elements.</p>

<p>Actually while we are at it, which of these are faster:</p>

<pre><code>li:first
</code></pre>

<p>or </p>

<pre><code>li:eq(0)
</code></pre>

<p>?</p>
