Step 1

In this workshop, you'll build a simple shopping list app to practice using the `useMemo()` and `useCallback()` hooks in React. You'll learn how to use these hooks to optimize the performance of your app by memoizing potentially expensive calculations and functions. All the basic HTML and CSS you'll need has been provided for you, along with the basic structure of a React component named `ShoppingList`. Within the `ShoppingList` component, return an empty pair of parentheses for now.
