Object-Oriented Programming in JavaScript

Writing scalable code in JavaScript requires a solid understanding of how objects, classes, and inheritance interact. If your scripts feel disorganized or difficult to maintain, adopting object-oriented programming (OOP) principles is the key to structuring your projects professionally. This text-based course guides you from foundational concepts to advanced architectural patterns in modern JavaScript. You will transition from basic functional scripts to robust, object-oriented applications. By reading through clear, step-by-step explanations and analyzing real-world code snippets, you will discover how to model real-world scenarios using code that is easy to extend, test, and debug. What you'll learn: - Understand the core pillars of OOP: encapsulation, inheritance, polymorphism, and abstraction. - Practice creating and configuring reusable objects using modern ES6+ class syntax. - Learn how JavaScript handles prototype-based inheritance under the hood. - Apply encapsulation using private class fields and modern getter/setter methods. - Design maintainable code structures using composition over inheritance where appropriate. - Implement type safety patterns and modern code organization with ES modules. This course begins with key terminology, basic concepts, and foundational definitions of objects and prototypes. You will then progress through the practical implementation of classes, encapsulation techniques, and advanced inheritance patterns. This course is designed for beginner to intermediate JavaScript developers who want to improve their code architecture. No prior experience with object-oriented programming is required, though a basic familiarity with JavaScript variables and functions is recommended.
