In Javascript, what does this syntax mean?
<p>I found this snippet when i was looking at jQuery plugins and wonder what it actually does</p>

<p>A jQuery plugin skeleton:</p>

<pre><code>(function($) {
    ... 
})(jQuery); 
</code></pre>

<p>And more recently in <a href="http://net.tutsplus.com/tutorials/html-css-techniques/building-persistant-sticky-notes-with-local-storage/?utm_source=feedburner&amp;utm_medium=feed&amp;utm_campaign=Feed%3A+nettuts+%28NETTUTS%29&amp;utm_content=Google+Reader" rel="nofollow">nettuts</a>:</p>

<pre><code>var STICKIES = (function () {
    ...
}()); 
</code></pre>
