Question

Accepted Answer

Redux is a predictable state container for JavaScript apps. It helps manage application state in a single immutable store.

Redux is a state management library for JavaScript applications.
It follows a unidirectional data flow architecture.
Redux architecture consists of actions, reducers, store, and middleware.
Actions are payloads of information that send data from the application to the store.
Reducers specify how the application's state changes in response to actions.
Store holds the state of the application.
Middleware provides a third-party extension point between dispatching an action and the moment it reaches the reducer.
The connect method in Redux is used to connect a React component to the Redux store.
The connect method takes up to four parameters: mapStateToProps, mapDispatchToProps, mergeProps, and options.
