FRP fits some problems better than others. User interfaces and networking are two event-based areas where it fits especially well. Not surprisingly, FRP is excellent for web applications.
RxJS—part of the Reactive Extensions suite—is a system widely used in web applications that has an FRP capability. In this chapter, we show how to use it for FRP by contrasting it against Sodium, which we’re treating as a model of true FRP.
Appendix C contains comparison charts for all the systems discussed here.
