YepNodeJS is a test-based javascript file loaded. I just heard about it in reading about Modernizr, which is a javascript library for supporting older browsers when implementing html5 features. Yepnope is built into modernizr, and I can see why. It allows you to conditionally load some javascript or css file if the browser supports it or load something different for older browsers. I had an immediate aha moment!!!!
I prefer to load jQuery and jQuery-UI from a CDN rather than a local file. The benefit of doing that is you aren't paying for that bandwidth, there is often a CDN closer to the user and thus faster, and often the user's browser already has a cached copy from that CDN. The problem is if you are disconnected from the internet when you are working on the site, you lose jQuery. Unless you were to conditionally load jQuery from local file if it was missing. A perfect usage of YepNopeJS, and it happens to be one of the examples on their home page.
