So you're curious in learning this new thing called (Functional) Reactive Programming (FRP).
The hardest part of the learning journey is thinking in FRP. It's a lot about letting go of old imperative and stateful habits of typical programming, and forcing your brain to work in a different paradigm. I haven't found any guide on the internet in this aspect, and I think the world deserves a practical tutorial on how to think in FRP, so that you can get started. Library documentation can light your way after that. I hope this helps you.
