JavaScript Classes: Instance Members, Static Methods, and Getters

Writing clean, object-oriented code is essential for large JavaScript projects. Classes provide the structure needed, but mastering the difference between data tied to an object (instance) versus data tied to the class itself (static) is key. By the end of this course, you will be able to confidently define classes that encapsulate behavior and data using the modern JavaScript standard. You will know how to manage object state using instance members, create utility functions using static methods, and protect internal data using private fields and accessors. What you'll learn: * Understand the foundational concepts of prototypes and the modern JavaScript class syntax. * Define and use instance properties and methods, correctly managing context using the this keyword. * Apply static properties and methods for class-level utilities that do not require object instantiation. * Implement getters and setters (accessors) to control how internal instance data is read and modified. * Practice using modern features like private class fields (#field) to ensure strong data encapsulation. * Configure classes for reusability using ES Module syntax (import/export). The course begins with foundational terminology and the core structure of a class definition. Subsequent modules guide you through defining instance state, adding static utilities, and implementing robust data protection using modern accessors and private fields. This course is designed for beginners who have basic JavaScript knowledge and are ready to start structuring their code using object-oriented principles. No prior experience with class syntax is required. Start building scalable and maintainable JavaScript code today.
