A TypeScript Fan's KotlinJS Adventures
summary
Built a playable Breakout clone in both TypeScript and KotlinJS using React, Redux and react-three-fiber to compare real-world costs and wins. TypeScript wins on community, npm interop and mapped/union types; KotlinJS needs manual wrappers or the converter ducat which produces imperfect unions and lost intersections. KotlinJS wins on coroutines and expressive DSLs and multiplatform sharing; bundle size and advanced TS type features remain the decisive tradeoffs.
