Kotlin 4 vs. Scala 3
summary
Scala 3 rewrites the compiler, emits a TST intermediate format, and adds union/intersection types, opaque types, top-level defs, extension methods, enums, significant-whitespace mode, exported delegation and compile‑time macros — a big language‑level expansion aimed at expressivity and metaprogramming. Kotlin 1.4 focuses on platform reach and stability: faster compilation, coroutines, serialization, JS and Native backends and multiplatform projects so shared business logic runs on JVM, Android, JS and iOS. Pick Scala for language innovation and research hacks, Kotlin for pragmatic cross‑platform delivery and teams.
