The Open/Closed Principle (OCP) is a golden rule of clean software design that says: “Software entities should be open for extension but closed for modification.” This means once your class or module is working correctly, you shouldn’t need to change its core logic when requirements evolve—you should extend it instead. In this tutorial, we’ll explore…
