Ask HN: Server-rendered web frameworks with static typing

I haven’t used this myself, but Reason seems to fit your description of ‘learning any language’ while having static typing: https://reasonml.github.io

I’m more of a lisper, but OCaml should be a fun learning experience, especially if you enjoy expressive, static type-systems: https://ocaml.org

Asp.Net core seems to fit your requirements

ok and then what keeps you from just using something like flow or typescript?

What is are you working with?

I appreciate you asking. I'm not working with anything in particular. This is for a personal exploratory project, and I can use any tool I want.
