Kotlin: Facts You Might Not Know
summary
Kotlin was created to interoperate with large Java codebases, compiling into mixed Java modules to avoid full rewrites while providing null-safety and the Nothing type to reduce NPEs; annotations like @Deprecated(ReplaceWith=...) can enable compile-time automated fixes. Reified generics with inline functions avoid runtime casts though JVM type erasure and proxies can still cause wrapped exceptions, coroutines became stable in Kotlin 1.3 (compiler and library), and a demo showed a Game of Life compiled to Native, JS and Android producing a ~1MB native binary that runs across platforms.
