#JavaScript typed functional langs:• @reasonml https://reasonml.github.io/ → #ocaml in js syntax• purescript @paf31 http://www.purescript.org/ → based on #haskell and syntax.• @elmlang http://elm-lang.org/ → is its own thing.
of these, i think #purescript will not go anywhere.elm is questionable due to new.reasonml of ocaml and facebook is probably the winner long term.
