TypeScript vs KotlinJS
summary
Compares concrete experiments: KotlinJS projects built from IntelliJ/Gradle producing webpack bundles, React + Redux + REST forms done both ways, and interoperability tested by writing Kotlin wrappers around npm libs. Finds TypeScript’s huge community and seamless JS interop gives faster, lower-effort results; KotlinJS yields Kotlin coroutines/suspending functions and expressive DSLs but needs manual wrappers and hits limits with unions/intersections. Dukat type generator exists but is Dukat type generator (experimental) and often requires hand edits; overall demos run, but TypeScript is the smoother path for production web apps.
