I end up having the same amount of tests in JS as in TS. I'm not really testing that the types are correct, but that functions work correct. So just because you're writing JS, doesn't mean that everything you would assigned types to in TS, you now write a unit test for itself. And my editor does the autocomplete thing seemingly just as well as the autocomplete I get from TS, even when I just write JS code normally.
