The interesting thing about React is that it's not at all incompatible with compositional event processing and true FRP. All it requires is that there be some concept of a "store" whose changes can be subscribed to, and the view and its children update automatically. That "store" can be a huge imperatively-driven series of Backbone.Collections, or it can simply be the end of a chain of compositional events using whatever structure or programming model you want. In many ways, it's a way for an application to decouple its view logic from its choice of event processing model. So you can start with a very simple view structure, and then with minimal refactoring you can swap out your event processing model for FRP as you need it. And it doesn't require your programmers to start thinking about type systems and immutability at the very beginning.

Do I have some gripes with React's API? Sure. But it's a good start.
