ReasonML Predictable Frontend Programming
summary
Compares ReasonML, JavaScript and TypeScript by showing concrete behaviors: type inference that deduces int usage from +, option/pattern matching that forces handling of none versus some, and how undefined/null differ from an option. Builds a working React app compiled with the BuckleScript compiler, formats with refmt, and uses the useReducer hook and dispatch actions for suggestion/reset/answer. Live demo compiles to JS, the app runs, and the examples reveal what actually changes versus just promising “examples.”
