Webb10 juli 2024 · Shared mutable state makes no sense in the real world. Yet this is exactly what happens in OOP programs — state is promiscuously shared between various objects, and they mutate it in any way they see fit. This, in turn, makes reasoning about the program harder and harder as the codebase keeps growing.
