no one writes JavaScript anyway.. ReScript: the ReasonML successor
ReScript is a robustly typed language that compiles to efficient and human-readable JavaScript. It comes with a lightning fast compiler toolchain that scales to any codebase size.
If you’re using a compiler and build step, you aren’t writing the code your users are running in the browser. If you need to “build” your web application, writing JavaScript is a choice. ReScript’s syntax allows developers to write type-sound, expressive, and readable code that still compiles to performant JavaScript, without the need for additional runtime libraries like Immer, ts-pattern, or rambda. If you’ve been keeping an eye on tc39 proposals, ReScript has features that have been stuck in tc39 proposals for years: do expressions, pattern matching, the Pipe Operator, and Record & Tuple values.
