What is the first functional programming language to choose?

Question

Functional programming

Good afternoon. I wanted to dive into FP. Advise which modern YaP is better to take. A mandatory requirement for a PL is active industrial use (i.e. communication with the user, working with the database, modeling) in the functional paradigm. Preferably with a non-overhead entry threshold. I tried to pick Haskell, but somehow I didn’t like it.

Answer 1

Take Scala ( wiki ).
Scala can interact with code written in Java and the code structure is close to Java/C#.

Answer 2

clojure. It is quite functional - it's Lisp (!), Only it is executed in jvm. Pretty industrial. You can write the backend, you can also write the front on clojure-script.

Answer 3

I advise kotlin, full support for everything that is in java (unlike scala) and a lower entry threshold

Answer 4

Erlang - simple as a boot.
