React JS Masterclass - Go From Zero To Job Ready - Redux Introduction

This lecture introduces Redux, a JavaScript library for managing state in applications. It addresses the problem of prop drilling and explains how Redux provides a centralized way to manage state consistently across components. The lecture also covers Redux Dev Tools for debugging, the integration of Redux with React using React Redux and Redux Toolkit, and the flow of actions, reducers, and store in Redux. Finally, it highlights how Redux Toolkit simplifies Redux logic by organizing it into slices.
