TypeScript Compiler

I remember that all I think about when you talk about like the closure compiler is see pre Google when TypeScript and Flow were beginning to flow around. And then it felt as far as my memory goes just one day, suddenly everyone was using TypeScript. To me, that always felt good and let you adopt incrementally,. Like especially once the Type Script supported JavaScript files, you could have 100,000 JavaScript files and one TypeScript file and the TypeScript compilation could take care of it all.
