jQuery objects as elements
<p>I see this syntax in some advanced jQuery:</p>

<pre><code>$container
</code></pre>

<p>as in:</p>

<pre><code>$input = $container.find('.fn_this_timeline')
</code></pre>

<p>EDIT: based on some of the comments below, just to clarify the first instance of '$container' that I can see is created right at the beginning:</p>

<pre><code>init: function($container){
var myThing = this,
$input = $container.find('.fn_do_some_calc'),
$submit = $container.find('.fn_do_some_other_calc'),
defaultValue = parseInt($input.val(), 10);

myThing.$container = $container;
</code></pre>

<p>The line above confuses me even more :/</p>

<p>I'm used to using jQuery selectors like this: $('#mySelector').method('etc');</p>

<p>Can someone let me know what the difference is and when it's appropriate or applicable to use the 'shorthand' style?</p>
