<p>I am a bit new to jQuery but have done some things with it. however i have never used jQuery() function and am curious what the purpose of it is.</p>

<p>Are these the same?</p>

<pre><code>jQuery("body") 

$("body")
</code></pre>

<p>What is the difference between?</p>

<pre><code>.data() and jQuery.data()
</code></pre>
