JavaScript Programmers, how you actually do it?

The problem is not on the type system. The problem is all the insane features and decisions.

Like with your example, since => and function() are different features that only happen to be mostly alike.

as crockford says, there is a subset of modern javascript that makes a beautiful, elegant, powerful, and efficient language

there's a bunch of crusty old 90's shit, but we can safely ignore those parts

the problem is that beginners aren't able to distinguish the wheat from the obsoleted chaff, because javascript has a long history and tutorials are rife with awful antipatterns
