genType VS rescript-sublime

I don't really use ts-belt to be certain, but by looking at the source, it seems that it's using genType, which can generate TS types from ReScript values, and that makes interop work really well.

They discuss this in their docs.

Seems like a type system for Javascript, built with a differing set of opinions than Typescript.

Looks like they also offer some form of TS interop:

TS Belt has been built with ReScript (and its Belt stdlib). ReScript generates highly performant JavaScript code, and with genType it also automatically generates TypeScript types. Moreover, I've added a few codemods to the building process to provide even more code optimizations and cleaner TypeScript signatures.

To interoperate with TypeScript with proper type information you’ll use third-party genType. Add it as a devDependency and annotate the module export you want to generate with @genType (in previous versions you’d surround annotations with square brackets).

ReScript devs did well on prioritizing the plugin for VSCode, which works really well. With the ReScript’s watcher running, you’ll see your Type errors underlined in red, with a descriptive bubble on hover. You also get type hints, formatting, and jumps to definitions. There’s also official support for Vim (both plain Vim and Coc Language Server) and Sublime.
