Introduction to Object-Oriented Programming (OOP) in JavaScript

As programs grow larger, organizing code becomes more important. Object-Oriented Programming (OOP) is a programming approach that helps structure code using objects and classes . OOP focuses on modeling real-world entities in code and encourages reusability, organization, and clarity . What is Object-Oriented Programming? Object-Oriented Programming (OOP) is a programming style where we organize code around objects rather than just functions and variables. An object represents something in the real world and contains: Properties → data about the object Methods → actions the object can perform Example: A person may have: name age city And actions like: introduce themselves walk speak OOP allows us to represent these structures in code. Real-World Analogy: Blueprint → Objects A good way to understand OOP is through a blueprint analogy . Imagine a car factory . A blueprint defines how a car should be built.
