ReScript community is well and alive and is actively working on improving the ReScript compiler and tooling. V10 just came out with records with optional fields - https://forum.rescript-lang.org/t/ann-rescript-v10-released/.... Async/await is in the works. The language is really really good (especially say comparing to TypeScript). Make sure to check it out.

ReScript is amazing. I really don't know much about the split (it's not like I didn't try to understand it, I just can't understand the anger of non-Ocaml developers at the split).

Rescript allows me to write Javascript in a sound type system, while remaining very close to how you would write code in Javascript.

Rescript to me feels like Typescript + a very prescriptive linting system which prevents a lot of problems, and since the linting system wouldn't let you do certain things, might as well get rid of them from the Type checker, this results in a much faster compiler.

I have been using ReScript for (almost) a year as a production programming language. There were a few limitations and confusions at first, (and I don't think it will be replacing TypeScript in any near future) but I can't even think about going back to a work environment uses TypeScript, the dev experience is so good :)

I think ReScript community is pretty active right now, I have big expectations about future 10.x releases (I'm working for a company uses ReScript as a main programming language) there are less buzz recently though.
