But I'd say it simply has a different scope: The Closure Compiler takes a subset of Javascript and creates highly optimized code. It optimizes the execution, not the development workflow.
Typescript forces you to think differently about the implementation itself. While the CC also imposes constraints on types and checks them during compilation, in the end I really just wrote Javascript (and sometimes pretty messy one).
In the end, I don't think either technology can be a substitute for code quality. But for me, with Typescript its certainly easier to produce a better coding style.
