Ruby the Pragmatic Way: From Foundations to Idiomatic Mastery

📖 Temario del Curso

• Section 1: Welcome to Ruby — Your First Steps in Code

  Begin your programming journey here. Discover why Ruby was designed around human ergonomics, start your first interactive session in IRB, and master core primitives.

  • 1.1 Saying Hello: Your First Conversation with Ruby
  • 1.2 Objects and Actions: Everything Has a Superpower
  • 1.3 Words, Numbers & Memory Boxes: Storing Your Ideas
• Section 2: Making Decisions & Talking with Users

  Teach your code to choose its own path with conditionals, explore multiple choices with case statements and ranges, and build your first interactive conversation with keyboard input.

  • 2.1 Making Decisions: Teaching Your Code to Choose
  • 2.2 Crossroads & Ranges: Choosing from Multiple Options
  • 2.3 Listening to Humans: Talking Through the Terminal
• Section 3: Collections & The Enumerable Pipeline

  Master ordered collections with Arrays, structured key-value data with Hashes, block iteration semantics, and functional transformations with Enumerable.

  • 3.1 Arrays: Ordering, Indexing & Bounds Safety
  • 3.2 Hashes: Key-Value Dictionaries & Name Badges
  • 3.3 Iteration & Blocks: The Enumerable Foundation
  • 3.4 The Transformation Pipeline: map, select & Symbol-to-Proc
• Section 4: Functional Craft: Methods, Blocks & Closures

  Master Ruby's functional tools: define clean, modular methods with keyword arguments, design custom block-yielding control structures, and encapsulate portable behavior in lambdas.
