Actually, adding the bare minimum of type annotations (fields & function signatures) and type casts (e.g. casting whatever you get from querySelector into the concrete type of element) results in fewer key presses, because you can auto-complete everything and because you get additional machine-assistance like call tips and type checks.

So, you'll be actually faster if you add some types. Type inference does cover quite a lot. In practice, you'll need very few annotations and casts.

This Dart demo, for example, only needed a single type cast to be fully typed:

WOW ! this code is impressive - do you have more examples like this?

Man type inference is so nice.
