A lot of those things are in a way a fundamental side effect of lenient languages and dynamism.

Having said I think it's definitely nowhere near as bad.

I use Typescript and modern JS and types and the modules/import system does a lot to prevent those things.

Because in general I don't have any globals lurking around so for example the styling of a component is imported at the top in the same file so it's always nearby. So the symbols and variables that you see on the screen are more obvious in terms of where they come from.

Redux also while not perfect if you have a reasonable amount of discipline it doesn't get as bad as the old-school stuff.
