Grocery list loop

Im having trouble writing a code that lets my program run in a loop to add more items to the list until I say "N". I've seen codes for this extra credit but honestly don't understand them and why they work. I'm hoping that someone can help me understand how to reference a method within another method and have it loop smoothly.

below is my code.

def create_list print "what is the name of the list? " name = gets.chomp.downcase hash = {"listname" => name, "items" => Array.new} return hash end def add_list_item print "what is the name of the item? " item_name = gets.chomp

print "how many? " quantity = gets.chomp.to_i

hash = {"name" => item_name, "quantity" => quantity} return hash add_new_item end def add_new_item

print "would you like to add another item? Enter: y or n: " add_new_item = gets.chomp.downcase if add_new_item == "y" return add_list_item else puts "you have created a list homie" end end

list = create_list() list["items"].push(add_list_item()) add_new_item
