And The Reason Is You
summary
Reason is a new syntax layered on 25‑year‑old OCaml that uses BuckleScript to emit idiomatic, human‑readable JavaScript; the compiler gives sound, 100%‑covered type checking with strong inference, algebraic data types and exhaustiveness warnings that list missing cases. Example builds show sub‑second native compilation for thousands of lines and generated JS with minimal runtime helpers (integers need wrapping), plain FFI for interop, and a React binding called ReasonReact; server native binaries are feasible—server startups as low as six milliseconds.
