Redux is a state management library for JavaScript applications, commonly used with React. It provides a centralized store to manage the state of an entire application, making it easier to debug and maintain.

Redux is particularly useful in large React applications where state needs to be shared across multiple components. It follows a unidirectional data flow, where actions are dispatched to update the state, and components re-render based on the updated state.

In full-stack development, Redux helps manage complex state logic, such as user authentication or API responses. For example, a React frontend might use Redux to store user data fetched from a Django backend, ensuring consistent state across the application.
