Reactive is a simple foundation for programming reactive systems functionally. Like Fran/FRP, it has a notions of (reactive) behaviors and events. Like DataDriven, Reactive has a data-driven implementation. The main difference between Reactive and DataDriven is that Reactive builds on STM-based IVars, while DataDriven builds on continuation-based computations.The inspiration for Reactive was Mike Sperber's [Lula] implementation of FRP. Mike used blocking threads, which I had never considered for FRP. While playing with the idea, I realized that I could give a very elegant and efficient solution to caching, which DataDriven doesn't do. (For an application
As with DataDriven, Reactive provides instances for Monoid, Functor, Applicative, and Monad.
