What Is Object-Oriented Programming?

Object-Oriented Programming (OOP) is a programming paradigm based on the concept of objects. Objects are instances of classes that contain properties and methods.

Key Concepts:

  • Properties: Variables that hold data specific to an object.
  • Methods: Functions that define the behavior of an object.

Tip: OOP makes your code more modular, reusable, and easier to maintain.
