This isn’t the type of answer you were asking for, but... Apprenticeship is invaluable. If you can, find an adept functional programmer to learn from. I was fortunate enough to get a job at a place using Elm and Elixir, and I had the opportunity to learn from another developer with a lot of passion for FP. It was incredibly helpful for learning. Good luck! FP is a great tool for your tool belt and teaches a lot about good code design.
