Boilerplate Javascript scripts/plugins?

Hmm I am not sure if these are applicable to "all" sites. We do recommend using good JavaScript patterns, but overloading a page with plugins is something I personally do not subscribe to :)

underscore.js. yepnope.js.

With the latter, it would be good if you used this to conditionally load plugins. Also it could be an idea to use module patterns for this boilerplate, possibly keep it namespaced.
