Modern JavaScript from the Beginning - Second Edition - Basic Principles of OOP

The video introduces the four basic principles of object-oriented programming: abstraction, encapsulation, inheritance, and polymorphism. Abstraction involves hiding unnecessary details to reduce complexity. Encapsulation bundles data and methods into a single unit, often hiding object states. Inheritance allows a class to inherit properties and methods from another class, promoting code reuse. Polymorphism enables methods to operate differently based on the object type, reducing the need for complex conditional statements. These principles are explained with relatable examples to aid understanding.

Describe inheritance and its benefits in programming.

What is polymorphism and how does it enhance code reusability?

Provide an example of polymorphism in object-oriented programming.
