We have looked into PYPL and TIOBE index now in December to rank the following functional programming languages in popularity: Clojure, Elixir, Erlang, F#, Haskell, Kotlin, OCaml, Rust, Scala and Swift.
According to TIOBE index the languages ranks like this:
The other languages that does rank in the TIOBE index from 51 to 100 are just in alphabetical order: Clojure, Erlang, F# and OCaml.
Note, no Elixir in TIOBE for December.
According to PYPL index the languages ranks like this:
That’s it, no more functional programming language rank.
Based on this, learn Swift, Kotlin or maybe switch from C++ to Rust?
We at Ada Beat will continue to support the MeetUp Func Prog Sweden throughout 2022.
Disclaimer, we choose to rank these functional programming languages based on what Wikipedia says is a functional programming language, what PurelyFunctional.tv lists and the author’s knowledge/preferences, which might not be the complete picture.
