I honestly don't think that there will be another framework that'll overtake react anytime soon. It's not about there being a better framework, just that we finally have something that's "good enough".

True. I used ExtJS and Ember for years and React just operates on another level.

I would say the same for Elm architecture and type system that guarantees no runtime exceptions. There is nothing similar in frontend languages and frameworks.

I think Elm is pretty cool too.

But last time I looked, the JavaScript integration did feel quite a bit more cumbersome than with Reason.

I’m looking seriously at ReasonML. I think it’s more promising than Elm.
