Sure, jQuery is bad at scale. And by "scale" I'm not talking pageviews, I'm talking features, development team, etc... For that, modular libraries like YUI and Dojo are the answer. You can create some of the most advanced web applications perfectly fine in JS as long as you approach it correctly.
P.S. Don't ever use the term "klocks" unless you want to sound like a enterprise middle manager who hasn't touched code in 20 years. Just a friendly tip. :)
Where are all the great JS tools and IDEs then? You simply cannot compare JS tooling to what can be had for a popular statically typed, inheritance based language. It's a whole different league.
P.S. Snide remarks such as that make you sound like a junior programmer who thinks he knows everything. Just a friendly tip ;)
