JavaScript Object-Oriented Programming: Building an Account Class

Object-oriented programming is a cornerstone of modern software development, allowing you to organize code into reusable, logical structures. If you want to write clean, maintainable JavaScript, learning how to model real-world concepts with classes is essential. In this written course, you will learn how to design and implement a fully functional Account class from scratch using modern JavaScript. You will move from understanding basic OOP terms to structuring secure objects that manage data safely. What you'll learn: 1. Learn the core principles of object-oriented programming in JavaScript, including encapsulation and abstraction. 2. Define custom classes with constructors to initialize object properties dynamically. 3. Create class methods to manipulate data, handle transactions, and update object states. 4. Implement modern JavaScript features like private fields and getter/setter methods to secure sensitive account data. 5. Practice writing clean, modular code through guided text-based exercises and step-by-step logic implementation. The course begins with foundational definitions of objects and classes before guiding you through constructing a robust Account class with secure data handling. This course is designed for beginners who have a basic grasp of JavaScript variables and functions and want to learn structured object-oriented programming. No advanced OOP experience is required.
