About this course

Understanding how to structure data and behavior is a fundamental milestone for any aspiring developer. Object-Oriented Programming (OOP) allows you to write clean, reusable, and maintainable code by organizing your logic into classes. This text-based course guides you through these essential concepts using practical, hands-on examples. In this course, you will transition from writing basic procedural scripts to designing robust object-oriented structures. You will tackle a practical coding challenge: building a functional bank account class from scratch, learning how to model real-world entities directly in your code. What you'll learn: - Understand foundational OOP principles, including encapsulation, classes, and instances in JavaScript. - Define class properties and constructor functions to initialize object state correctly. - Implement robust methods to handle actions like crediting, debiting, and describing account status. - Apply modern JavaScript features such as private fields to secure sensitive account data. - Practice writing and debugging class structures through comprehensive written exercises and code breakdowns. The course begins with key terminology and the foundational concepts of classes and objects. You will then progress step-by-step through designing, coding, and testing your own bank account class using modern JavaScript syntax. This course is designed for beginner JavaScript developers who want to transition from basic syntax to object-oriented programming. No prior OOP experience is required. Start reading today to elevate your JavaScript skills and build cleaner, more structured code.
