It's almost like python and typescript are used by different people for different purposes and have therefor developed differently, but some features end up being an overall good idea which enrich their respective ecosystems.

You sound like an absolute tool.

[Edit: Who f*cking cares]

I’s amazing how often people celebrate some new feature in a language and I’m like: TypeScript has been doing this for years now.

Whatever another programming language supports or does is entirely irrelevant if what you're working with is Python.
