As a swe that works with typescript / javascript, I find this post exhausting.

Am I the only one? Am I a shit swe?

Edit - comments seem to suggest I was asking this question seriously. I was not, I was just (sort of) joking.

That being said, front end engineering is rapidly changing all the time, so the confidence I have in knowing I will always have work to do (read that to mean: a job) is satisfying.

I don't think it's that bad but I wish they'd focus more on improving the terrible JS web API rather than adding language features.

I mean they are adding features like static initialisation blocks when we only just got String.replaceAll(), and they somehow managed to fuck that API up despite it being explicitly a replacement for an existing bad API!

Where are all the containers? Sorted sets/maps? Why can't I even map an iterator?

That's W3C’s job, not ECMA’s.

Sets and Maps are sorted (by insertion order)

It's coming, but someone will likely be exhausted by that addition. https://github.com/tc39/proposal-iterator-helpers
