Usage of [0] with visual effects in jquery
<p>Why selecting via [0] in jquery does not work with visual effects??</p>

<pre><code>$("p")[0].slideUp(); /* it does not work*/
$("p").eq(0).slideUp(); /* it works */
</code></pre>

<p>As mentioned, I know there are some other ways to select the first p, but I am eager to know why the above mentioned code is not working... </p>

<p>Thanks in advance,</p>
