What is Functional Reactive Programming?
summary
Defines FRP as a time-focused, functional-style abstraction that represents continuous state as behaviors and discrete occurrences as events, with concrete Haskell examples. Shows combinators like when and map, folds event streams into state, unions update streams, and renders UI or simulation outputs; implements Game of Life in about 20 lines by composing inputs, combinators, and outputs. Claims this approach cleanly separates state, updates, and observations and scales to UI, robotics, and simulation.
