ReasonML: Syntax Extension and Toolchain for OCaml

ReasonML is a syntax extension and toolchain for OCaml that focuses on simplicity, performance, and JavaScript interoperability. It allows developers to write simple, fast and type-safe code that compiles to JavaScript.

What is ReasonML?

ReasonML is a syntax extension and toolchain for the OCaml programming language that focuses on simplicity, performance, and seamless JavaScript interoperability.

As a syntax extension, ReasonML provides an alternative syntax to OCaml that is designed to be simpler and easier to learn, while remaining fully compatible with existing OCaml code. The goal of ReasonML is to make OCaml more approachable for JavaScript developers by providing syntax that feels familiar.

In addition to the syntax extension, ReasonML also includes its own toolchain for compiling OCaml/ReasonML code down to performant JavaScript. This allows developers to write application code in OCaml/ReasonML that leverages the safety, speed and expressiveness of a typed functional language, while still being able to run that code in the browser and integrate well with existing JavaScript codebases.

Some key capabilities and benefits of ReasonML include:

  • Simple, intuitive syntax
  • Seamless JavaScript interoperability
  • Fast compilation times
  • Type safety and error checking
  • Great performance
  • Minimal runtime overhead
  • Easy migration for existing OCaml code

ReasonML continues to gain popularity as a way to build highly scalable, safe and fast front-end applications. Companies like Facebook, Messenger, Slack, and Vercel use ReasonML in production to power complex web experiences.
