TypeScript, a transpile-to-JavaScript language, is one of the fastest growing new languages on GitHub. With the inventor of C#, Anders Hejlsberg, as one of creators behind it, TypeScript has had 100% year-on-year growth. And since April, it has surpassed Dart and CoffeeScript on Google trends. It certainly has significant usage in the .NET community given its Microsoft origins, but its strong typing is probably the biggest draw.
