do I need to create a method?

for this I need to create a method?

shopping_list.rb
grocery_list = { 'title' => 'Grocery List', 'items' => [] }
grocery_item = { 'title' => 'Bread', 'quantity' => 1 }

grocery_list['items'] = grocery_item

Liviu Tudor you don't need to create a method, but since your grocery_list value for the items key is an array, you need to add to that array using the push method or using <<. So your code would look like this:

grocery_list['items'].push(grocery_item)

or

grocery_list['items'] << grocery_item

Let me know if this does the trick for you! ?
