Kotlin is a statically typed, object-oriented programming language for the JVM and the browser. (There are also versions based on JavaScript.) It resembles Apple's Swift language, but preceded it. It can be used for client or server side development, as well as to create Android apps similarly to the use of Swift to create iOS apps. It was developed by Russians.

Variables and structures in Kotlin come in mutable and immutable varieties, indicating whether their values can be changed after being set for the first time.

The Kotlin keyword for defining a function is 'fun', so programming in Kotlin is clearly more fun than with any other language.
