jQuery is undoubtedly useful when dealing with browser quirks, but once an application grows over a few thousand lines of code, unstructured jQuery code simply becomes too difficult to maintain, and you start needing the discipline of a framework to organize code.

I cannot stop to suggest you to give it a try.
