Kotlin

Kotlin is a modern programming language, open source and statically typed. It targets Java Virtual machine, Android and javascript. It is a general programming language with functional features, used by Google, Amazon , Netflix and many more companies. 

It combines object oriented and function programming features. It allows fast and safe development for android apps. So Kotlin permits you to write code that is expressive and concise, safe, and interoperable. Even if a big part of android professional developers use Kotlin to develop android apps, it also can be used for server side, web, native and desktop development.
