Ruby treats almost everything as an "object." This means you can create custom blueprints called to represent real-world things, making code easier to reuse and manage. : Ordered lists of items, like a shopping list

💡 : Learning Ruby isn't just about the language itself; it’s about learning to think like a computer scientist. For a deeper dive into these topics, the Computer Science Programming Basics in Ruby guide by O'Reilly provides a structured curriculum for absolute beginners.

Programming starts with understanding a problem and breaking it into a series of logical steps called an algorithm. : Analyze and understand the problem. Step 2 : Write the solution in plain language (pseudocode). Step 3 : Translate that language into Ruby code. Step 4 : Test and debug the code in a real environment. 2. Variables and Data Types
