About this course

Are you confident in Ruby, or has it ever surprised you with a tricky behavior you didn’t expect?Welcome to Tricky Ruby Questions, a hands-on puzzle-based course designed to help you uncover and truly understand Ruby’s quirks, hidden features, and elegant design principles.Ruby is a beautiful language — expressive, flexible, and powerful — but it also hides subtle behaviors that can surprise even experienced developers. This course transforms those hidden aspects into fun, interactive puzzles that help you think like a Rubyist and gain mastery through reasoning, not memorization.You’ll explore concepts step-by-step, learning why Ruby behaves the way it does, not just what it does. Each section is built around real-world code examples, tricky snippets, and conceptual challenges that mirror what developers face in production or during technical interviews.We’ll start with core foundations — variable scope, nil, and truthiness — before diving deeper into Ruby’s dynamic heart:Arrays, Hashes, and Enumerables — master data iteration and transformationMethods, Blocks, and Closures — understand yields, procs, and lambdas clearlyObject Orientation — work with classes, inheritance, modules, and selfMetaprogramming — explore send, method_missing, and eval for dynamic codeReflection and Constants — peek behind Ruby’s flexible internalsBy the end, you’ll not only solve puzzles — you’ll think like Ruby itself.You’ll understand how Ruby executes, how methods resolve, how objects communicate, and how dynamic behavior emerges elegantly from simple rules.This course is ideal for Ruby and Rails developers, interview candidates, and curious programmers who want to deepen their understanding and sharpen their problem-solving skills with Ruby.Get ready to code, think, and debug like a true Rubyist!
