Said it before and will again. I think TC39 has done a remarkably good job evolving JS. So many of the additions over the last ~15 years feel like so nice – like natural obvious additions to the language that just fit in with everything else, without adding new dimensions of complexity. The way promises + await + `try/catch` snap together is an old example I have always loved. But the way `Iterable`, `Iterator`, `Generator` and `for of` all fit together is another really pretty one. So is `class` + `prototype`. I know there was prior art to look at for a lot of this, but I still think that fitting this all together with the world's largest ecosystem of existing code and developers must have been quite a challenge. Props and gratitude @TC39.
