Really? I think a lot of people find the opposite to be true about Javascript, in terms of source. Javascript allows for some fun magic, but that pretty quickly cuts into readability/debugability. Look at Bluebird -- works great, but not just a "I'll jump right in here and understand it" sort of module.

You're definitely right about the C# docs, though. I always feel totally lost looking through those, especially since I'm not much of a C# dev to begin with.
