It took 6 years to ship ES6. We've now had a new spec iteration from every year after 2015. They are moving much, much faster and, having lived through ES5 to much pain and angst, I'm completely ok with them taking their time shipping these (very nice to have) features.

Is it JavaScript's job to improve the lives of transpiler implementers instead of improving the lives of JavaScript developers?

I think they’re saying that TS won’t add the feature until JS does. Still kind of a strange take IMO, but makes a little more sense.

First of all Typescript, is now more mainstream JS dialect than vanilla-js itself and, honestly, the only one i care about.

And i thought it's kind of obvious for anyone, that until *JS* proposals are staged far enough - Javascript won't have those features too. There is a good reason why TS waits for the stage 3.

I mean you still can't even call `find()` or `contains()` on an iterator. JavaScript developers just collect them into arrays. :-/

no coroutines no buy

Generators are basically coroutines, aren't they?
