🛡️ Generate Accessors with attr_accessor

Ruby’s attr_accessor, attr_reader, and attr_writer are simple metaprogramming shortcuts for defining getter/setter methods. Instead of writing boilerplate, list attribute names and let Ruby auto-generate the methods.

class User
  attr_accessor :name, :email
end

u = User.new
u.name = "Carol"
u.email = "carol@example.com"
puts u.name   # => "Carol"
