Thanks for the heads up about RxJS, didn't know that existed.
Seeing as one of the benefits of React is in server-side rendering, and now with the new OSS nature of .NET, it's worth considering standard Rx as well ( https://msdn.microsoft.com/en-gb/data/gg577609.aspx ).
Rx is very new to me, so I may have this description wrong, but it essentially seems to be well-supported event-driven programming library. Worth a look if you're interested in FRP.
Rx isn't FRP, and doesn't really solve the same problem that react does (view management). Its grew for pushing discrete events around, but doesn't provide for any signals and continuous binding.
