Beginning Object-Oriented Ruby: Classes and Methods

Every program in Ruby is built around objects, making object-oriented programming the core foundation of the language. To write clean, maintainable, and idiomatic Ruby code, you must understand how classes, methods, and variables interact. This text-based course takes you from foundational concepts to building structured, reusable code. You will start by learning essential terminology and core object-oriented principles, then move step-by-step into creating your own custom classes and defining methods. You will also explore modern Ruby conventions, including type safety concepts and clean variable scoping. What you'll learn: Understand the core principles of object-oriented programming in Ruby; Create custom Ruby classes and instantiate objects; Define methods with parameters, return values, and modern keyword arguments; Manage state using instance, class, and local variables; Implement inheritance and mixins to reuse code efficiently; Apply clean coding conventions and modern Ruby formatting practices. This course begins with fundamental definitions and conceptual frameworks before guiding you through structured text-based exercises and code walkthroughs. It is designed entirely for beginners with no prior object-oriented programming experience. Start your journey toward writing professional Ruby code today.
