I'll take your assessment at face value (although a quick look at github repos, it seems that junit is way larger).
My point wasn't to ship crap, it was about obsessing on quality over actually shipping (and cutting some corners). This is something I learned at my first job, we obsessed over quality and never shipped. Guess what happened? :)
The code, imo, is some of the highest quality js I've seen. It is also incredibly comprehensive and easily as complex.
High quality != shipping fast. They are separate quantities, it is easy to have one without the other but very rare to have both.
