You can configure typescript to make typing optional. With that option set, you can literally rename .js files to .ts and everything "compiles" and just works. Adding this feature to nodejs means you don't even have to set up tsc if you don't want to.
But if I were putting in type hints like this, I'd still definitely want them to be statically checked. Its better to have no types at all than wrong types.
