Learn Basic OOP by Building a Shopping Cart - Step 1

Tell us what’s happening:

To start, you will need to get some of your elements from the DOM. Start by using document.getElementById() to get the#cart-container, #products-container, and #dessert-card-container elements. Store them in variables named cartContainer, productsContainer, and dessertCards, respectively.

Since these will not change, remember to use const to declare them.

So I did what was asked, didn’t work. Then I refreshed the tab, reset the lesson, and hard refreshed. Didn’t work. What should happen here?
