Where can I find other, similar javascript libraries, frameworks, or engines?
<p>I recently came across <a href="http://fgnass.github.com/spin.js/" rel="nofollow"><strong>spin.js</strong></a>. And I just realized how much can be done with javascript. It left me wondering about other awesome javascript frameworks out there that I may not know of. I wanted to created a list here for others to consult. And hopefully to learn about a few new interesting javascript projects myself, too.</p>

<ul>
<li><a href="http://api.jquery.com/" rel="nofollow"><strong>jQuery</strong></a></li>
<li><a href="http://jqueryui.com/" rel="nofollow"><strong>jQuery.UI</strong></a></li>
<li><a href="http://developer.yahoo.com/yui/" rel="nofollow"><strong>YUI</strong></a></li>
<li><a href="http://nodejs.org/" rel="nofollow"><strong>node.js</strong></a></li>
<li><a href="http://fgnass.github.com/spin.js/" rel="nofollow"><strong>spin.js</strong></a></li>
<li><a href="http://lesscss.org/" rel="nofollow"><strong>less.js</strong></a></li>
<li><a href="https://github.com/mishoo/UglifyJS/" rel="nofollow"><strong>uglify.js</strong></a></li>
<li><a href="http://sizzlejs.com/" rel="nofollow"><strong>sizzle.js</strong></a></li>
</ul>

<p>I'm more interested in specific-application libraries like spin, node or less than actual frameworks like jQuery, YUI or Dojo, etc.</p>
