Master polymorphism and interfaces in object-oriented programming. Learn compile-time vs runtime polymorphism, method overloading and overriding, interface-based design, duck typing, and the Liskov Substitution Principle with practical examples in TypeScript, Python, and Java.
Master the fundamental building blocks of object-oriented programming. Learn the difference between classes and objects, dive deep into abstraction with abstract classes and interfaces, and understand constructors, static members, and access modifiers with practical examples.
Explore three distinct approaches to defining and enforcing contracts in code: duck typing (Python, TypeScript), explicit interface implementation (Java, C#), and implicit interface implementation (Go).
