What is Functional Reactive Programming? (Tikhon Jelvis)

How can we work with time in functional programming? Traditionally, reactive systems—UIs, web servers, robotic controllers, simulations—are seen as inherently imperative, not suitable for functional programming. This does not have to be the case! Functional Reactive Programming (FRP), lets us have our cake and eat it too: we can use the composable, declarative style we love as functional programmers to write this kind of code. But what is FRP? It's surprisingly hard to get a clear answer without diving deeply into research literature. I will give you an introduction with practical Haskell examples that will get you over the hump to understanding and using FRP.
