Kotlin

Kotlin is a statically typed procedural programming language in the CPL branch of the Algol family that runs on the JVM. It is reminiscent of both Java and C (and to a lesser degree C# & C++), but goes out of its way to fix some of the problems inherent in these languages and with special emphasis on safety, making some of it features structurally reminiscent of languages in the Pascal branch (Modula-3, Zonnon et al). It also has stronger object-orientation features than either Java or C++.

One unusual aspect of the language is that in addition to compiling to the JVM it can also compile to ECMAScript and can therefore be used to develop browser applications and applications for devices like the iPhone that do not feature a Java implementation.

The language can interact with any Java based library or tool.
