I know that my syntax is off. I have tried looking back at the video, but it just isn't clear to me how this works. I know I need to return true if there are no elements in the array, and false if there are; but how do I check the array? I thank you all for your time and help to make this community so awesome.
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 |item|
if item == 0
return true
else
return false
item += 0
end
end
end

if todo_items.length == 0
return true
else
return false
end
Hope this helps.
