Learn to Code with Ruby

Master Ruby and object-oriented design in this advanced course built for developers who are ready to take their programming expertise to the next level. Through 15 in-depth modules, you’ll move beyond the basics to write clean, reusable, and maintainable code while developing the skills to build and scale complex Ruby applications. Your journey begins with an exploration of blocks, procs, and lambdas, where you’ll learn how to write flexible code and work with advanced features like the yield keyword, return values, and custom iterators. You’ll then dive into classes and object design, mastering hierarchies, variables, method overriding, and encapsulation with private and protected methods. Next, the course expands into inheritance, modules, and mixins, showing you how to extend functionality and structure applications effectively. Along the way, you’ll apply best practices for robust design and gain hands-on experience with file I/O, sets, and date/time manipulation. The final modules take you into practical development workflows, including regular expressions, exception handling, testing with Minitest, writing documentation, and managing Ruby gems. Each section emphasizes not just technical detail but also professional practices that prepare you for real-world development challenges. By the end of this course, you will have: - Mastered Ruby’s advanced features, including blocks, procs, lambdas, and iterators. - Built a strong understanding of object-oriented design, inheritance, modules, and mixins. - Practiced core development tasks such as file handling, regex, and testing. - Developed the skills to design and maintain complex Ruby applications with confidence. This course is designed for experienced Ruby developers who are already comfortable with the language’s syntax and fundamentals. If you’re ready to level up your programming expertise and build maintainable, production-ready Ruby projects, this course will give you the tools to succeed. Updated in May 2025. This course now features Coursera Coach — your interactive learning companion that helps you test your knowledge, challenge assumptions, and deepen your understanding as you progress.

This course is designed for those with a foundational understanding of Ruby seeking to elevate their skills. - It begins with string operations, exploring differences between single and double quotes, multi-line strings, and string concatenation, while also covering string comparisons and manipulations. - Control structures are introduced next, including various loops and conditional statements with practical examples like the FizzBuzz problem. - You'll learn to implement while and until loops, use keywords like next and break, and delve into recursion. - The final sections cover debugging and advanced array methods, teaching you to use tools like the debugger and binding.break, and exploring array iteration methods like each, map, and select. - You'll also cover ranges, strings, Hashes and explore how object references and copies work in Ruby. The course is ideal for developers with basic Ruby knowledge looking to deepen their expertise and improve problem-solving abilities. This approach combines theoretical explanations with practical applications, featuring hands-on coding exercises and real-world examples.
