What does $.request and $.fn.redirect and $.redirect mean in jQ?
<p>I'm looking at this .js file and the jquery looks like:</p>

<pre><code>$.fn.redirect
$.redirect
$.request
</code></pre>

<p>or</p>

<pre><code>(function($){$.log=function(message){if(window.console){if(window.console.debug)
window.console.debug(message);else if(window.console.log)
window.console.log(message);}
else
alert(message);};
</code></pre>

<p>Are these built-in jQuery methods or is it custom?
Just trying to understand this notation.</p>

<p>Is (function($){}; a way to start of your .js file?</p>
