About this course

Every value in Ruby is an object, but understanding how these objects are constructed, classified, and manipulated is the key to writing clean, maintainable code. This text-only course guides you through the core concepts of object-oriented programming in Ruby, demystifying how instances relate to their parent classes. You will transition from writing simple scripts to designing structured, reusable code using modern Ruby conventions. What you'll learn: Understand the foundational relationship between Ruby classes and instances; Inspect object behavior and trace inherited methods through the lookup path; Define custom classes with attributes, initializers, and modern encapsulation practices; Apply inheritance to share behavior efficiently across different object types; Practice writing clean Ruby code using modern type hints and standard formatting conventions. Starting with essential definitions and core object-oriented theory, the course moves step-by-step into hands-on code analysis and practical structure design. This course is designed specifically for beginners who have a basic grasp of programming logic but want to master Ruby's object model with no advanced prerequisites required. Start reading today to unlock the true power of object-oriented Ruby.
