Hi classmates,
def print_list(list)
puts "List: #{list['name']}"
puts "---"
list["items"].each do |item|
puts "item " + item['name']
puts "Quantity" + item['quantity'].to_s
puts "---"
end
end
and
list['items'].push(add_list_item())
why I cant use double quote across for all method? what's the difference between using single quote and double quote?
Thank you
