Brief Introduction to ReasonML
summary
ReasonML is presented as a new syntax for OCaml that compiles to JavaScript via BuckleScript, offering 100% type-safe guarantees, fast builds, and JavaScript interop (externals and inline JS). Examples include a reducer-style counter using variant types and pattern matching that catch missing cases (6 combinations from a boolean × three animals), CSS-in-JS with typed props, and real-world adoption: Facebook migrated much of Messenger to this stack and games like graviton compile to native successfully.
