Ever since I've started writing Objective-C, a lot of Javascript's glaring issues have started to melt away. Yes, JS doesn't have an understanding of protocol, but that's just a matter of implementing convention and being disciplined. JS is remarkable in that it is so malleable that one can use myriad patterns with it.
I've found that the delegate pattern, for instance, can be incredibly powerful when used in conjunction with JS, especially when it comes to extending classes functionality that may not be inherent to its topology (think class Ant, to describe an Ant, and class FlyingAnimal -- wings, etc. --, to describe a queen ant).
