Cart Reducer and Add to Cart Action

The video tutorial explains how to implement a cart functionality in a JavaScript application. It covers creating constants for cart actions, developing a cart reducer to manage state, and implementing an 'add to cart' action using Axios for API requests. The tutorial also discusses saving cart data to local storage and retrieving it to initialize the application state.
