How does object oriented JavaScript impact performance? How does an object oriented solution compare to a procedural solution performance wise?

The short answer is minimal if any. There are several assumptions made regarding your question...first, that the code written is optimal itself. The main benefit of using OO JavaScript in my opinion is the ability to utilize polymorphism and design patterns in JavaScript. While I have not read anything stating there is overhead with loading the source, I can imagine that there is more overhead, than if the script was contained in the body to begin with, but that would defeat the purpose to begin with, since another desire is to modularize your code so you dont have cut-n-paste snippets everywhere.

totally agreed with B Webb! This would be a micro-optimization and chances are there are other ares that give you "more bang for your buck".

I posted some more optimization thoughts in this thread
