initialize_method

🎯 Define initialize

The initialize method runs automatically when you call .new. Use it to set up instance variables with default values or required parameters.

class Person
  attr_reader :name, :age

  def initialize(name, age)
    @name = name
    @age = age
  end
end

p = Person.new("Carol", 25)
puts "#{p.name} is #{p.age} years old."  # => "Carol is 25 years old."
