React JS Masterclass - Go From Zero To Job Ready - Filter: Context and Reducers / 111

The video tutorial focuses on implementing filtration using context and reducer in a project. It begins with setting up folders for context and reducers, followed by defining an initial state with properties like product list, sort by, and ratings. The tutorial then explains creating a context and provider, and how to use the useFilter hook to access context data. Finally, it covers the structure of a reducer and handling various cases for product filtration.
