ReasonML: React as a Language and what the Future looks like
summary
A visual mobile app builder (Draftbit) runs a compiled compiler in the browser and a WebAssembly phone preview, with layers gradually ported from JavaScript to Reason for fewer runtime errors and much faster feedback. The stack uses Reason/OCaml + BuckleScript to target JavaScript, Expo + React Native, GraphQL/Apollo and Postgres; GraphQL cuts ~30% server and ~70% client code in this workflow. BuckleScript compiles in milliseconds and enables aggressive tree-shaking (immutable.js 55KB → 899 bytes).
