Dart

Dart is an object oriented language optimized for user interface creation. It is an open source general-purpose programming language that compiles to native machine code as well as to javascript language. So it can be used to develop apps for any platform. It is also static typed and it allows safe programming. 

Dart core libraries already provide the essentials for many programming tasks. It can be used to develop mobile apps as well as to build servers and desktop applications. Developed and used first by Google, it is now used by other companies as Alibaba , and  WorkTrails.
