About this course

Object-oriented programming in JavaScript has evolved, and understanding how to structure your code using modern syntax is essential for any developer. This course provides a clear, step-by-step path to mastering class structures and inheritance patterns in modern JavaScript. You will transition from writing disorganized scripts to designing clean, reusable, and maintainable code architectures. By focusing on modern standards, you will build a solid foundation in software design principles that you can apply directly to real-world projects. What you'll learn: - Understand the core concepts of object-oriented programming and prototype-based inheritance in JavaScript - Create robust classes with constructors, properties, and custom methods - Implement class inheritance using the extends keyword to share functionality across objects - Use the super keyword correctly to invoke parent constructors and access overridden methods - Apply modern JavaScript features including private class fields and static methods for better encapsulation - Practice structuring clean application state using modern object-oriented patterns The course begins with foundational concepts, defining key terminology and explaining how JavaScript handles objects under the hood. You will then progress through practical, written examples that guide you from basic class declarations to complex inheritance hierarchies. This course is designed for beginner to intermediate JavaScript developers who want to write cleaner, more structured code. No prior experience with object-oriented programming is required, though a basic familiarity with JavaScript variables and functions is recommended. Start reading today to elevate your JavaScript coding standards.
