I've been building a FP style framework very similar to OM & Elm in plain javascript ( https://github.com/Raynos/mercury ).

It has some of the core features

- immutable data - immutable vdom - global state atom, no hidden local state. - no manual DOM manipulation code (read or write). - a single top down flow of data from input to output - Events and Signals from FRP that can be manipulated using pure higher order functions.

etc.

As a bonus it's very modular, so if it doesn't fit your needs at least some subset of it will.
