Research fa fa cart item counter in nav bar for

[jpantana]

User Story

As a user, when I click "add to cart" button, a cart icon in the top left of nav bar should be incrementally counting with each item

AC

WHEN i click "add to cart" THEN a cart icon in nav bar should have a number that incrementally counts reflecting how many individual items are in my cart

Development

• link rel for font awesome
• position the fa fa class in the nav bar accordingly
• call a function when cartArray is printed to the dom (e.g. cartIcon();)
• function should looks something like:
  • const cartIcon = () => { let num = array.length; printToDom('cardIconId', num);};
• possibly adding the data-count="" to the html will be of use (maybe 🤷🏻‍♂️)

For this case you shouldn't need a counter. Just use the cart.length. You will always want this number to match the number of things in your array exactly. Please rework the development section to account for this change
