Sounds like you are mostly frontend. I can highly recommend ReScript https://rescript-lang.org/ https://rescript-lang.org/ I learned a lot about functional programming from it. It is a more frontend focussed https://reasonml.github.io/ https://reasonml.github.io/ which is all based on OCaml. It has the same awesome type system and all the FP goodies while providing easy TS/JS interop and convenient escape hatches. It compiles (very fast) to highly efficient readable JS that you can use wherever.
