Replacing ifs with ternaries and switches with cond are hardly significant or important changes. The whole point of abstraction (functional or object-oriented) is to push that logic from control structures in code to composition structures in runtime data. If you weren't replacing conditionals with polymorphism, you weren't doing object-oriented programming in the first place.
