confused about the difference between ReasonML, Melange, and ReScript?
- ReasonML is an alternate syntax for OCaml
- Melange is a compiler from OCaml to JavaScript
- ReScript evolved from a fork of the OCaml compiler with changed the syntax and has a great ecosystem for web dev

ReScript is awesome because you can drop it into any JavaScript project and use any JavaScript runtime.
I'm currently working on a project using Deno and it works great!

i want something like @rescript-lang.org but for @lean-lang.org. that is, a JavaScript backend emitting reasonably idiomatic JS code. i wonder whether this is structurally impossible.

The Rescript, once recited at schools nationwide, was abolished in 1948. Abe Toshiko, Japan's Minister of Education, says it's unconstitutional. That's not an issue for Sanseitō! The words appear as part of its Emperor-venerating "New Japanese Constitution."

ReScript, ResGraph and pgtyped-rescript is quite neat for building GraphQL servers 😍
Full type safety from DB to client, minimal boilerplate, all more or less "just ReScript".
