This chapter introduces Object-Oriented Programming (OOP) in JavaScript, a powerful way to structure and organize code for large and professional applications.
OOP helps developers create reusable, maintainable, and scalable programs by organizing code into objects and classes instead of scattered functions.
Modern JavaScript uses OOP concepts in frameworks, libraries, and backend systems such as React, Angular, Node.js, and Express.
In this chapter, students will learn how to:
- Understand what OOP is and why it is important
- Create objects in JavaScript
- Use classes and constructors
- Work with methods and properties
- Understand inheritance and code reuse
- Use encapsulation for better code safety
- Apply OOP concepts in real-world projects
By the end of this chapter, students will be able to write structured, reusable, and professional JavaScript code — a major step toward becoming a job-ready developer.
