Kotlin Native

Technologie um Kotlin Code zu nativen Binaries zu kompilieren, die ohne VM laufen.

  • Bestmögliche Integration in existierende Systeme
  • Einfache Anwendung
  • Nützliches Tooling

Kotlin Multiplatform

Technologie um Kotlin Code auf unterschiedlichen Plattformen
wiederzuverwenden.

  • Interoperabilität
  • Maximale Code Wiederverwendung
    • Über ein Kotlin Common Modul

Kotlin Multiplatform 

internal expect fun writeLogMessage(message: String, logLevel: LogLevel)
internal actual fun writeLogMessage(message: String, logLevel: LogLevel) {
    println("[$logLevel]: $message")
}

Common

        LogLevel.DEBUG -> console.log(message)
