About this course

Building scalable software requires a solid architectural foundation, yet many developers struggle to structure their application data effectively. This course guides you through the process of organizing your application logic using robust object-oriented patterns. You will transition from writing scattered functions to designing clear, reusable model classes that manage your data and business rules seamlessly. By reading through clear explanations and structured code examples, you will learn how to model real-world relationships and manage data flow within your applications. You will gain a deep understanding of how to represent entity relationships, implement inheritance, and connect your in-memory models to persistent storage engines. What you'll learn: - Understand the core principles of object-oriented design and how they apply to modern JavaScript - Design robust model classes to encapsulate application data and business logic - Implement class hierarchies and inheritance structures using clean subtyping patterns - Configure data retrieval and saving strategies to connect your models with data stores - Apply modern JavaScript features such as private fields, getters, setters, and static methods - Practice structuring clean application code that is easy to maintain and test The course begins with foundational concepts, defining what model classes are and why they are essential for clean architecture. From there, you will explore inheritance, subtyping, and practical strategies for loading and saving model state. This text-only course is designed for beginner to intermediate developers who want to improve their software design skills. No advanced architectural experience is required, though a basic familiarity with JavaScript syntax is recommended. Start writing cleaner, more structured JavaScript today.
