ReasonML to JS or Typescript or Flow? Which one you love?

I think, both Flow and Typescript contributed to a better JS ecosystem. Nowadays it's more TS than Flow.

Both are also gateway drugs to using real statically typed languages like Elm or ReasonML.

And since I use Reason for nearly 2 years already (1 yr in production), I gotta say I love it very much. Never looked back to JS with Flow or TS.
