Object-Oriented Ruby: Classes, Objects, and Methods

Ruby is a pure object-oriented language where almost everything is an object, but unlocking its true power requires a deep understanding of how classes, objects, and methods interact. If you want to write elegant, idiomatic Ruby code rather than just translating syntax from other languages, mastering these core concepts is essential. This text-based course guides you from the fundamental definitions of objects to designing your own robust classes and reusable methods. You will learn how to structure your applications using Ruby's unique object model, preparing you to write clean, maintainable, and modern code. What you'll learn: Understand the core philosophy of Ruby's object-oriented paradigm, starting with basic definitions and terminology; Create custom classes and instantiate objects to model real-world concepts; Define methods, handle parameters, and leverage modern features like keyword arguments and safe navigation; Apply encapsulation principles using public, private, and protected access modifiers; Practice writing idiomatic Ruby code that adheres to modern style guides and best practices. The course begins with foundational definitions and key terminology before advancing to hands-on structural design. You will progress from writing simple scripts to crafting organized, class-based programs through written explanations and code exercises. This course is designed for beginners new to Ruby or programming, as well as developers looking to solidify their understanding of object-oriented design without any complex prerequisites.
