JavaScript OOP: Class-Based Inheritance and Logic with Triangles

Object-oriented programming is a cornerstone of modern software development, yet transitioning from basic syntax to structured class design can feel abstract. This course bridges that gap by using intuitive geometric concepts to teach you how classes, constructors, and inheritance work in practice. You will learn how to structure data, share behavior across objects, and implement clean algorithmic logic to solve real-world coding challenges. By reading through clear explanations and structured code examples, you will transform your understanding of how objects interact and how to organize your application code efficiently. What you'll learn: - Understand the core principles of object-oriented programming and class-based inheritance in modern JavaScript - Create robust base constructors for general shapes to share common properties and methods - Extend classes using inheritance to build specialized constructors for triangles - Implement logical conditions to accurately identify and classify equilateral, isosceles, and scalene triangles - Apply modern JavaScript features like encapsulation, clean getters, and basic unit testing principles using Jest This course begins with foundational definitions of object-oriented concepts before guiding you through step-by-step code construction. You will start with simple shape properties and gradually layer on inheritance, custom methods, and validation logic. This text-based course is designed for beginner JavaScript developers who want to move beyond basic functions and master clean, object-oriented code architecture. No prior experience with classes or inheritance is required. Start reading today to build a solid foundation in JavaScript object-oriented design.
