— It literally could not do so because of the way the code would have to be designed, it's not run-time type checking

Iterators are a great example of type safety in practice, because they standardize a data structure's serialization, meaning the code which prefers to rely on iterators is "more" type safe

— People at my workplace say that adding something i.e type safety to current workflow and adopting to that will slow it down

— And in a way it is thinking over something that i rather not have without considering type safety so there is some cost of time

— Now how much it would be and the will benifits outweigh the cost that i don't know yet

— Where is the time cost?

— Type safety in JS can be incrementally added

— So it's optional everywhere

— Additional step of thinking and adding type safety where its good to have but not needed

— Yeah that's true

— Which step?

— I don't see it
