How do you ask if @todo_items has NO Elements in the Array

How to equate @todo_items array to having no elements?

todo_list.rb 
class TodoList
  attr_reader :name, :todo_items

  def initialize(name)
    @name = name
    @todo_items = []
  end

  def add_item(name)
    todo_items.push(TodoItem.new(name))
  end

  def empty?
    if @todo_items 
      return false
    else
      return true
  end

end

There is a method called "empty?" that returns true or false if there are no elements. So, if you add

return @todo_items.empty?

that will return true or false depending on if the array is empty or not.
