There are a number of Haskell-to-JS compilers and Haskell-alike languages which more directly target JS. This is growing quickly but major issues remain and the toolkits are quite immature. On the other hand, much of React is a natural play out of Haskell's sweet spot. The challenge will be in making Js-alike APIs which handle the flexibility well while maintaining sufficient typing. React-like rendering, virtualdom, data flow... this will all be incredibly naturao.
