OOP in JavaScript

Object-Oriented Programming in JavaScript allows developers to model real-world entities using objects, prototypes, and classes JavaScript supports OOP through prototype-based inheritance and modern ES6 class syntax, enabling cleaner and more intuitive object creation . It emphasizes key principles like encapsulation, inheritance, and polymorphism to build scalable applications. Methods can be attached to objects or defined within classes for reusable behavior. JavaScript’s dynamic nature makes OOP flexible, allowing both classical and functional programming patterns to coexist.
