React JS Masterclass - Go From Zero To Job Ready - Reducer / 088

The video tutorial covers the implementation of a card reducer in a React application. It explains the use of useReducer for managing state and dispatching actions to update the cart list and total. The tutorial demonstrates how to add and remove items from the cart using dispatch and provides a detailed walkthrough of integrating these methods into the app. The session concludes with a summary and outlines future tasks for updating totals and refining the app.
