Ruby Programming For Everyone

Explore arrays as containers that hold multiple values, using zero-based indices to access items, check length, and retrieve last items; learn about multi-dimensional arrays and printing elements.

Explore while loops in Ruby by building a counter, looping while the condition is true, printing numbers 1 through 9, and avoiding infinite loops with proper increment.

Learn how to use the each loop to iterate over ranges and arrays in Ruby, printing numbers and names with a block and puts, and understand naming conventions like underscores.

Explore hashes in Ruby, comparing them to arrays, using keys and values with the hash rocket and square-bracket access to retrieve data like John's pizza preference.

Learn to build fizz buzz in Ruby by looping 1 to 100 and using modulus with if/elsif to print fizz, buzz, or fizz buzz.

Explore methods in Ruby, defining with multiple parameters, passing variables, and handling argument counts. Learn returning values, storing output, and transforming results with downcase and upcase.

Explore Ruby classes as blueprints that produce objects, and learn to navigate the Ruby core docs and the Ruby API to discover string and array methods.

Define a Ruby class with a capitalized name, implement initialize to accept a side_length and store it in an instance variable, then inspect the square object.

Ruby programming for everyone guides adding perimeter and area methods to a square class, computing perimeter as four times the side and area as side squared, with a two_s report.

Explore how Ruby's attr_accessor automates getters and setters, reducing boilerplate for multiple attributes in a class, demonstrated by a square's side length and a simple test.
