Optional is great and I'm siding on building APIs on the user-land side if possible.

Unfortunately, having n different libraries basically doing the same thing is just annoying. This thing you call "competition" is just developers egos gone berserk. There's no point in building 2 things that do the same thing, unless it's definitely better (which is good) or unless the point it conveys is "I'm better than you" (which most devs are, really). I mean look at this guy who tries to overtake jQuery 10 years after jQuery started: https://github.com/drduan/minggeJS/blob/pr/95/README_en.md

That said, Lodash and Underscore should just merge. Zepto and jQuery should just merge. Immutable and Mori should just merge. Inferno and React should just merge.
