Jquery Evolution from simple plain javascript
<p><br/>
i have been using jquery for a while now but only thing i know about jquery is probably a dozen of functions that get my job done. but i want to understand how jquery evolved from simpl plain javascript i.e how</p>

<pre><code>$("#xyz").val();
</code></pre>

<p>is converted to </p>

<pre><code>document.getElementById('xyz').value;
</code></pre>

<p>i have searched for my answer on the web but most of the writers are happy to show how you can hook on to different DOM elements with jquery, selector details etc. but nothing can be found about how actually the transition was made. can anyone refer me to some tutorial where i can get my required material?<br/>
thanks</p>
