I’ve been using Haskell in production for three years and it’s been great so far!

I think these concepts translate to other languages fairly well, and are easy to learn in Haskell:

- Newtypes (Languages like Kotlin/Swift have support for them, and you can kinda get close with lots of classes in Java)

- Purity (can write “pure” code in most languages)

- Algebraic Data Types (help with thinking about modeling data, works in eg TypeScript)

- Maybe / Optional types (Now very popular in other languages)

- Parser Combinators (work in eg JavaScript)
