React JS Masterclass - Go From Zero To Job Ready - Redux Store State / 094

The video tutorial covers accessing and managing cart information using Redux in a React application. It explains how to use the useSelector hook to access the cart list and its length, implement conditions for adding or removing items, and utilize useEffect to update the cart state. The tutorial also demonstrates logic for displaying add or remove buttons based on the cart state and visualizes cart changes. Future topics include discussing Redux terms and deploying the application.
