jQuery code works without jQuery library
<pre><code>src="http://code.jquery.com/jquery-latest.min.js" charset="utf-8"&gt;

function switch01(){
    $("#con01,#con02,#con03").hide();  
    $("#con04").slideToggle("slow");
};
</code></pre>

<p>As I understand, the above code is jQuery code, and it needs the first - reference line to work at all.<br>
For example, CSS code will not work without a reference to a css file (if not inline placed).<br>
But I removed the first line (accidentally), and what I see - the code still works.<br>
Does maybe browser has jQuery inside itself ?<br>
If so - why one can need the above line at all ?<br>
And if so - what about priority issue (in case version's conflict between the referencing and browser's library ?<br>
And, if not so - where is the library placed ?<br>
Maybe - in the eternal, ever-present Universe :).<br>
Or maybe - something is wrong in my understanding (probably).</p>
