Typescript is pretty much the gold standard, it’s amazing how much JavaScript madness you can work around just on the typechecking level.
IMHO Python should shamelessly steal as much typescript’s typing as possible. It’s tough since the Microsoft typescript team is apparently amazing at what they do so for now it’s a very fast moving target but some day…
Well the TS tooling is more painful in ways. It's not compatible with some stuff like the NodeJS profiler. Also there's some mess around modules vs "require" syntax that I don't understand fully but TS somehow plays a role.
