It's an interesting podcast, but wanders a bit, and there's no transcript. But does mention Jordan Walke who wrote the first prototype of react for Facebook ads. Jordan is currently working on reasonml:
I do wonder if it'd be easier to port sml syntax to ocaml rather than make reasonml - I guess not. But it might give similar benefits: a pleasant syntax dialect for ocaml, a mature compiler for js and native, and bringing in th js and ocaml library ecosystems.
[ed: but not, perhaps, 90% overlap with js syntax.]
As I mentioned - I haven't really played with reasonml/reason-react - I think maybe some of the impressions alluded to in my first comment came in part from this:
"When using ReasonML, we don’t need Redux anymore. ReactReason stateless components already come with the concept of a build in reducer, which is meant to take care of the problems Redux used to address."
You might not need this library, especially so in a language which provides good enough construction blocks out of the box. ReasonReact already comes with reducers!"
I didn't realize they didn't start with ocaml, but sml.
