Why ReasonML
Reason lets you write simple, fast and quality type-safe code while leveraging both the JavaScript & OCaml ecosystems.
Why OCaml?
- General purpose language (1996) used in critical systems
- Facebook is using it in several projects (Flow)
- Functional programming language with Hindler-Minler type system
- Can be compiled to bytecode, native code or JS
-
Performance and compilation time is blazing fast
- A language for writing React (first React prototypes were in SML)
- While being functional it still has escape hatches
- Amazing community
- compiles === works
- Amazing tooling in the language itself
just take a look at JavaScript world
