I'm in the boat of learning FP right now. What would really help me, and folks in the same process, is for people to suggest languages that _would_ be better, and why, instead of doing the stereotypically HN commenter thing that I'm already seeing.
I always recommend https://www.coursera.org/learn/programming-languages for learning FP, the professor has fantastic explanatory videos that are really clear and concise. You'll get the most out of it from doing the exercises, but you can still take away a lot from just watching the videos.
