Your equivalence with transpiling coffeescript is false. TS doesn't really have "syntactic sugars". Just about everything in it(less the types of course) is pretty far along in the ES adoption process. There are a couple exceptions like decorators that are called out in a very visible manner.

If you target ES6 your code may look identical. Even much of the ES5 down leveling produced code that looks like a person wrote it.

I converted a 10k line coffeescript project(with async/await !) to JS and then TypeScript. The similarities are so far apart they might as well be in different dimensions. But, if you don't want to take a rando posters word for it, it's pretty easy to make a little sample project and see if the output is to your liking.
