I just started to learn Ocaml to learn functional programming. I will use it to build a CLI that’s mostly orchestrating other programs.
My experience is mostly in JS / TS, but I’ve also coded a good bit in Python and Lua.
Below, I provided a list of things I learned or focused on while using OCaml. But I feel like I must be missing something. This is only moderately different from what I’m used to in JS. I expected something more radical. Moreover, I constantly hear a lot of FP jargon (like “highly kinded types”, monads, etc) that I feel am still missing.
So far, here’s what I studied:
immutability
avoid side affects
static typing
recursion instead of loops
option / maybe
higher order functions
conditionals and other constructs as expressions, when they’re statements in other languages

If you’re posting long videos try to add in some form of tldr for those who don’t want to watch videos
Algebraic datatypes is a huge part of typed functional programming for me, you should read up on that!
