Reason, also known as ReasonML, is a general-purpose, high-level, multi-paradigm, functional and object-oriented programming language and syntax extension and toolchain for OCaml created by Jordan Walke, who also created the React framework, at Facebook.[3][4] Reason uses many syntax elements from JavaScript, compiles to native code using OCaml's compiler toolchain, and can compile to JavaScript using the ReScript compiler.[5]

BuckleScript and ReScript
editReason was originally compiled to JavaScript using the BuckleScript compiler,[7] which was created at Bloomberg L.P.
In 2020, the BuckleScript and Reason toolchain was rebranded to ReScript, essentially creating a separate language that had different syntax from Reason and only compiled to JavaScript.[8]
BuckleScript was forked to Melange[9] to continue to support compiling OCaml to JavaScript.
