Even "make it work" is debatable.

I'd say when ES6 landed. I used to hate JS, but since ES6, I think it's a pretty good language for building frontends.

ES6 is indeed pretty good, all things considered, but GP specified javascript tooling, which, uh, could still use some work before it's considered truly "good".

I'd say ES5 made it work and ES6+ made it good. I think by the time the Pattern Matching, and Record & Tuple proposals are completed and implemented it'll go to fast.

to be fair they didn't say it has completed the progression through that program.

This got a genuine laugh from me. Stockholm syndrome is a prerequisite for writing JS
