AWS, JavaScript, React - Deploy Web Apps on the Cloud - Rendering the Categories

In this video tutorial, the instructor guides viewers through the process of improving a React-based web store by creating a separate category component. The tutorial covers the use of arrow functional components, passing props, and destructuring in React. It also addresses common errors and demonstrates alternative methods for mapping data. The video concludes with a preview of adding an onclick event to fetch products by category.

What was the initial improvement made to the store's website?
