  • Which functional programming language should I learn?

    3) Finally, Scala 3 + cats is a great middle ground. It's a great language to teach and learn FP, even if you learn by yourself, without support from other people. There are lots of materials and even if you get stuck with a concept, you can still implement it using what you knew before.

    On the contrary, switching to the functional mindset, with something like Typelevel Scala3 and respective cats and cats-effect fs2 frameworks, helps to rethink a lot of designs and development approaches.
  • Question about some advanced types

    You want Kernmantle, which quite honestly shouldn't be hard to implement around Cats and cats-effect. In particular, although Kernmantle doesn't require the use of the Arrow typeclass, there happen to be Arrow (actually ArrowChoice) instances for both Function1 from the standard library and Kleisli from Cats itself, given a Monad instance for the Kleilsi's F[_] type parameter. In other words, we should be able to port Kernmantle from Haskell to Scala (with the Typelevel ecosystem) and instantly be able to use pretty much anything else from the Typelevel ecosystem, or wrapped with it, in our workflow graphs. Pure functions, monadic functions, applicative functions, GADTs with hand-written interpreters, any of it. I think this would be eminently worth doing.
  • Thanks to Rust Kotlin makes me like JVM

    If you want to use simple straightforward scala https://www.lihaoyi.com/ did a lot for the ecosystem creating simple libraries not forcing fp. For fp look at https://typelevel.org/cats/ though I won't recommend diving too deep in the rabbit hole, I know lots of people swear by it, but I think it just overcomplicates code for few tangible benefits (code being pure and guaranteed free of side effects means little to me). It's is fun to get things working though, much less maintaining/migrating old code)

    If I managed to gain you interest you can take a look at one of the following libraries like cats, scalaz for scala and vavr for java which contain type class definitions and implementations for common types.
  • Junior developer looking for a Haskell codebase to work on and a mentor to help me

    Scala is like a cross between Java and Haskell. Scala has a notation for monads similar to Haskell's `do ...` notation. It has libraries like (cats)[http://typelevel.org/cats/] (the name "cats" is short for "category theory") for functional programming. It has immutable classes with copy constructors similar to Haskell's records. Both languages have implicit parameters. I like immutability and strong type systems.

    Cats is a library which provides abstractions for functional programming in the Scala programming language. The name is a playful shortening of the word category. https://typelevel.org/cats/
