I think this is somewhat funny since to think of this question at all really highlights the time people waste in JS/python etc.. Testing things that can be automatically checked by a simple compiler.

I do find that as some of these people migrate to TypeScript they write too much tests, as they are just not used to have some checks already done for them.

But to others that come from compiled/typed languages that's a question you'd never ask :)
