Foo Hack » YUI’s “Module Pattern” vs. Prototype’s Class Function

Interesting perspective, with which I agree somewhat. Though, there's certainly something to be said for building a domain-specific language of convenience for DOM manipulation. "The more time someone spends building applications with a library like Prototype, the further they get from Javascript, and the more dependent they become on the library. By contrast, time spent using YUI tends to breed developers who are experts in Javascript, and that skill is far more useful than being an expert in a particular library."
