General Development "Everyone seems to have a replacement for JavaScript - Google even has two.

TypeScript is a superset of javascript (just like c++ is a superset of c), with means, that Javascript is 100% compatible with TypeScript

Except C++ is not a strict superset of C, which means that C is not 100% compatible with C++. I.e. there are C programs which either are not C++ programs, or have a different meaning in C++.
I hope TypeScript does a better job at being a superset. But then, if you're 100% compatible with JS you get all the crazy stuff like this:

In many cases the C's weak type system does implicit conversion, while C++ requires an explicit cast due to a stronger type system.

The ?: has a different priority order due to grammar issues.

Finally, after C89 and C++98 each standard group went its own way.
