Free Pathway

Free Pathway — A Free Start in Ruby
Free Pathway is a free course designed for those who are just beginning to explore Ruby or want to build a solid foundation before moving to more advanced topics. It helps you understand the internal logic of the language, not just its surface syntax.
Many people start with simple examples like “hello world” but face difficulties when reaching real tasks. Free Pathway lays a strong foundation: it explains why almost everything in Ruby is an object, how the naming system works, and why certain behaviors differ from other programming languages.
This is an opportunity to explore the Lumiruby approach without commitments and evaluate the structure, explanation style, and course logic.

What’s included in Free Pathway:
4 structured modules with step-by-step explanations
Lessons with detailed code examples and in-code comments
Exercises after each module for independent practice
Materials available through a personal cabinet
Downloadable code examples

Course Structure
Module 1: Ruby as an Object-Oriented Language from the Beginning
Understanding why Integer, String, and Array are objects.
Explaining self in the top-level context.
Introduction to open classes and the basics of monkey patching.

Module 2: Type System and Dynamic Nature
Practical use of duck typing.
Difference between nil, false, and empty values.
Understanding object_id and frozen objects.

Module 3: Symbols vs Strings — When It Matters
Comparing symbols and strings.
Memory and performance considerations.
Practical examples of using symbols as hash keys.

Module 4: Blocks as a Core Ruby Mechanism
Working with yield.
Passing blocks using &block.
First steps toward understanding Proc and Lambda.

After completing Free Pathway, you will be able to:
Understand Ruby’s object model and how it affects code
Use symbols and basic types more consciously
Write methods that accept blocks and understand their role
Avoid common beginner mistakes related to nil, frozen objects, and object behavior
Evaluate whether Ruby’s philosophy fits your learning goals before moving to the next level

Who this course is for
Suitable if you:

  • Have already tried programming in any language
  • Want to understand why Ruby behaves the way it does
  • Plan to continue learning through the next Lumiruby levels

Not suitable if you:

  • Are looking for a very short overview without deeper thinking
  • Want to jump directly into web development without understanding the language itself

Free Pathway is a structured starting point in Ruby that helps you see the language as a whole and build a solid foundation for further skill development.
