React JS Masterclass - Go From Zero To Job Ready - Cart: Context and Reducers / 124

The video tutorial guides viewers through setting up a cart system using React's context and reducer. It begins with creating the cart context and reducer files, followed by defining the initial state with a cart list and total. The tutorial then covers building the cart context and provider components, implementing the useCart hook, and setting up the cart reducer with actions like add, remove, and clear cart. Finally, it demonstrates integrating the cart provider into the app, ensuring cart data is accessible throughout. The session concludes with a brief summary and a look ahead to the next lecture.
