Object-Oriented Programming in Ruby

Writing clean, maintainable software requires more than just understanding basic syntax; it demands a solid grasp of how to structure your code. This text-based course introduces you to the core principles of Object-Oriented Programming (OOP) using Ruby, a language designed from the ground up to be purely object-oriented. You will transition from writing simple scripts to designing robust, modular applications. By reading detailed explanations and analyzing practical code examples, you will learn how to model real-world problems into elegant software structures. What you'll learn: - Understand the core pillars of OOP including encapsulation, inheritance, polymorphism, and abstraction - Create and configure Ruby classes, initialize objects, and manage state with instance variables and accessors - Implement inheritance to share behavior and use modules and mixins for flexible, multi-class code reuse - Apply modern Ruby conventions such as type hints, keyword arguments, and proper file structuring - Practice writing clean code by refactoring monolithic scripts into cohesive, decoupled objects This course begins with fundamental definitions and essential terminology, ensuring you build a strong theoretical foundation before moving on to practical code design. You will explore step-by-step written walkthroughs that demonstrate how to organize files, manage dependencies, and write testable Ruby classes. This course is designed specifically for beginners and developers transitioning from procedural programming. No prior experience with object-oriented design is required.
