Cross-platform

Building React applications with Reason is a lovely experience and, what's more, since OCaml is able to compile to native, we will be able to use these same skills to build apps that compile to assembly, iOS/Android, and much more. In fact, Jared Forsyth has already created a game called Gravitron (https://github.com/jaredly/gravitron) that compiles to iOS, Android, web, and macOS from one Reason codebase. That being said, the frontend JavaScript story is much more polished as of this writing.
