Just like @klodolph said, TypeScript to JavaScript is what C++ is to C, I.e it offers SUBSTANTIAL benefits while there are still some dark sides of the language to be discovered. (My personal view: TS metaprogramming is the hardest for me so far, enum mess, Babel TS preset lacking metadata support etc)
