Reason - Simple, fast & type safe code that leverages the JavaScript & OCaml ecosystems

Reason lets you write simple, fast and quality type safe code while leveraging both the JavaScript & OCaml ecosystems. Reason is not a new language; it's a new syntax and toolchain powered by the battle-tested language, OCaml. Reason gives OCaml a familiar syntax geared toward JavaScript programmers, and caters to the existing NPM/Yarn workflow folks already know.
