Reason, also known as ReasonML, is a syntax extension and toolchain for OCaml created by Jordan Walke, who also created the React framework, at Facebook.[2] Reason offers a syntax familiar to JavaScript programmers, and compiles to native code using OCaml's compiler toolchain. Reason code may also be compiled to JavaScript using the ReScript compiler.[3]

The Reason community officially provides ReasonReact as a solution for React-based web applications.[4]

BuckleScript and ReScript

Reason was originally compiled to JavaScript using the BuckleScript compiler,[5] which was created at Bloomberg L.P.

In 2020, BuckleScript was rebranded to ReScript, essentially creating a separate language that had different syntax from Reason and only compiled to JavaScript.[6]

The ReScript compiler continues to support Reason syntax, and the two languages share that part of the toolchain.
