The author mentions DefinitelyTyped: "DefinitelyTyped typings amount is just insane and it will take time for ReasonML to match them." I agree it would be nice to have an expert analysis of a reasonably-sized application, but that is a rather large undertaking. And frankly many devs aren't experts in two "competing" ecosystems. If you spend the bulk of your time in ReasonML, you're apt to fall behind on TypeScript's recent developments. What you see as bias may just be simple ignorance. I've just started playing around with ReasonML in the past week, and everything the author has hit upon has been relevant. Writing reducers in ReasonML is a treat. But, the language server isn't nearly as good and there aren't many annotated libraries, so I have to fall back to BuckleScript's JS interop support. The interop system is well-done, but it's extra overhead I wouldn't have to deal with otherwise.
