For example, yes callbacks were very messy but very soon we will have generators. And, yes, the scoping was nasty but soon we will have the 'let' keyword. I cannot remember where I read it, but I do also remember seeing a talk about some proposals to extend "use strict" to allow people to fix some of the type-casting behaviours made infamous by wat, too.
My point isn't that everything is fixed and we can stop complaining about the bad parts. My point is that it is very impressive how those in charge are handling the evolution of the language.
I think it's worth taking a bet on a language which improves so much every year.
