Not OP, but I would recommend backboneJS[1] or underscore[2]:

The .NET framework is fantastic at this, you don't even need the underlying code, usually just the function signatures and Visual Studio autocompletion allows you to guess your way into finding the right classes and functions. Everything has long descriptive names (without the AbstractProxyFactory bloat from Java), follows conventions, arranged in a logical hierarchy and ample documentation available in intellisense.

I’m willing to bet that descriptive names is a red herring, and the real difference in code quality were engineers who cared enough to review for such things.
