Derive state from localStorage

[ivan-unfolds]

You don't need this state, you can just derive it from what's in local storage

week6-missmacs/pages/index.js

Line 21 in 7cd5ff6

const [itemsInBasket, setItemsInBasket] = useState(0);

So something like

const itemsInBasket = JSON.parse(localStorage.getItem("basket")).length

I spoke last week about having as little state as possible and deriving data you need for your UI from the it. This is an example of that, let me know if that makes sense!
