Acknowledgments

• Thanks to the OCaml team, obviously, without such a beautiful yet practical language, this backend would not exist
• Thanks to ninja-build, ReScript also comes with a blazing fast build tool on top of it, ninja is a truly well engineered scalable build tool
• Thanks to Bloomberg and Facebook. This project began at Bloomberg and was published in 2016; without the support of Bloomberg, it would not have happened. This project's funded by Facebook since July/2017

ReScript builds on parts of js_of_ocaml:

• jscomp/core/js_dump.ml (pretty printer)

ReScript builds on parts of OCaml:

• jscomp/core/lam_pass_exits.ml
• jscomp/core/lam_pass_lets_dce.ml

These modules were adapted from ocaml/bytecomp/simplif.ml for JavaScript specific optimization purposes.

• jscomp/main/js_main.ml

jscomp/main/js_main.ml is adapted from ocaml/driver/main.ml. It is the main entry point of the underlying compiler.

• jscomp/stdlib-406

jscomp/stdlib-* is copied from ocaml/stdlib. It is compiled to JavaScript and included with ReScript.

• jscomp/test

jscomp/test is based on ocaml/testsuite.

ReScript unit test builds on parts of OUnit

• jscomp/ounit is adapted from ounit, the unit test utilities are only used for dev purpose, they are not required for distribution
