How well does Babel transpile TS? My initial instinct is that I'd trust the real TS compiler over Babel, but I've never tried compiling TS with Babel.

I assume the real TypeScript compiler still does the type-checking and that would be unaffected by Babel.

The TS team implemented the TS parsing support in Babel. You are correct that the TS compiler is still needed for the typechecker, however.
