I could see how that's a legitimate concern, it reminds me of some of the complaints I hear about C++ having too many features (I don't use C++, so this is just hearsay). But Javascript is still a much smaller and simpler language than almost anything else out there. Sure, it has some semantic quirks, but the syntax is fundamentally minimal. I think it will be a long time yet before we reach the point of being really overcomplicated.

I think the uncertainty around Javascript (and I do agree that there seems to be a real sense of confusion in the community when you look at the explosion of libraries and frameworks) is more related to the fact that we are trying to solve hard problems in a language that really gives us no help. We get no type checking, no good concurrency APIs, no immutability, no good sequence abstractions until iterators, just a fairly low-level and extremely hackable language with an unusual prototypal inheritance system.

Well, who knows. I would personally like to see some more stuff be standardized in the language or the official APIs so we don't end up with four competing libraries implementing "map" and "reduce", or promises, or whatever other thing.
