Polymorphism allows objects to be treated as instances of their parent class, enhancing flexibility.
Polymorphism enables a single interface to represent different underlying forms (data types). For instance, in an e-commerce application, both `DigitalProduct` and `PhysicalProduct` can be treated as `Product`. This allows you to write code that works on the `Product` type, and it will work for all product types, increasing flexibility and reducing code duplication.
