Ruby Booleans Challenge 1

This has me stumped! Help please!! Would you please make your answer as plainly as possible I am really stuck.

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?
    todo_items.each do |todo_item|
      if todo_item.name == name
        found = true
      end
      if found
        break
      else
        index += 1
        end
    end
    if found
      return index
    else

  end
end

Hi Sara,

If the array is empty, it should return true otherwise return false, see examples below.

# Example 1
  def empty?
    if todo_items == []
      true
    else
      false
    end
  end

# Example2
def empty?
  todo_items.empty?   # this method will return true if array is empty
end

Hope that helps, however, you can appreciate people who take time to explain to the questions, please always use best answer option to let other members know solutions available. :)
