Code question.

You will come across attr_reader, attr_writer and attr_accessor while working with Ruby. The first line is creating a class called Todoitems. I have recreated an example of that class

class Todolist
  attr_reader:name, :todo_item

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

end

list = Todolist.new("Mike", "Shoe")
puts list.name
puts list.todo_item

You can see that I am able to call list.name and list.todo_item. This will return "mike" and "shoe" the reason I have access to these variables is because of that method. A really helpful way to break it down is to jump behind the scenes and take a look at what that method is actually doing.

class Todolist

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

end

list = Todolist.new("Mike", "Shoe")
puts list.name
puts list.todo_item

This code is essentially the same as above. But instead of having to define a todo_item method and a name method we can just uset the attr_reader method instead.
