How to cleanly initialize attributes in Ruby with new?

Question

class Foo
  attr_accessor :name, :age, :email, :gender, :height

  def initalize params
    @name = params[:name]
    @age = params[:age]
    @email = params[:email]         


        

Answer 1

Why not just explicitly specify an actual list of arguments?

class Foo
  attr_accessor :name, :age, :email, :gender, :height

  def initialize(name, age, email, gender, height)
    @name = name
    @age = age
    @email = email
    @gender = gender
    @height = height
  end
end

This version may be more lines of code than others, but it makes it easier to leverage built-in language features (e.g. default values for arguments or raising errors if initialize is called with incorrect arity).
