The article cites papers for some of the architectures, and FRP papers have been around since the 90s. AFAIK the first mention of "functional reactive" is FRAN, written in Haskell, in 1997. TBAG was close enough to the idea (maybe closer than most JS implementations!), in C++ in 1994. For papers see http://conal.net/papers http://conal.net/papers
