Kotlin

Kotlin is a programming language developed by JetBrains. Originally shaped as a programming language based on the Java platform and JVM, Kotlin was designed with Java interoperability in mind, meaning that a Kotlin program can use not just the Kotlin Standard Library but the Java SE API and all Java libraries too, and Java programs can call useful helpers in the Kotlin Standard Library and all sorts of other Kotlin code as well. Later, Kotlin has been expanded with Android support, JavaScript support with Kotlin/JS, and support for native machine code as compiler target via Kotlin/Native.
