React JS Masterclass - Go From Zero To Job Ready - Condition Check: Already in Cart / 127

The video tutorial covers the implementation of a product card with add and remove functionality, using React's useEffect for state management. It explains how to handle cart state, manage dependencies, and implement button logic for adding and removing items. The tutorial also extends these functionalities to the product detail page and updates the checkout page with total calculation. Finally, it discusses implementing protected routes to restrict access to logged-in users and accessing user information during checkout.
