Unlock Ruby with the "Zero-to-Hero" Notion Roadmap. This is not a syntax cheat sheet — it is a complete, interactive textbook of 30 chapters that takes you from your first puts to building your own Rake-style tool.

Whether you're a Rails developer wanting the language underneath, a scripter automating daily work, or a beginner drawn to Ruby's famous readability, this template gives you the depth and structure to master Ruby with confidence.

What’s inside

  • Foundations — objects, variables, control flow, methods, and the everything-is-an-object mindset that makes Ruby click
  • Collections — arrays, hashes and symbols, and string handling used the idiomatic way
  • Blocks, Procs & Lambdas — the heart of Ruby, plus the Enumerable module that powers elegant data pipelines
  • The Object Model — attr_accessor, inheritance and super, and sharing behavior with modules and mixins
  • The Ruby Way — metaprogramming and method_missing, community idioms, and the culture that shaped the language
  • Robust & Real — exceptions, file handling, gems and Bundler, and testing with Minitest
  • "Try Every Possibility" code, trap-annotated — idioms and the famous traps marked # BROKEN: and # ILLEGAL:, so you meet them in safety first
  • A practice challenge + a harder bonus in every chapter — with hidden solutions and a dedicated Challenge Answers chapter
  • 5 Capstone Projects — TaskTrek, WordFreq, FlashQuiz, ShopCart, and TaskDSL, with a hidden sixth to discover
