Redux Toolkit is a set of tools that helps simplify Redux development. It provides a number of utilities that make it easier to create and manage Redux stores, reducers, and actions. Some of the features of Redux Toolkit include: Simplified store configuration: Redux Toolkit provides a function called configureStore() that makes it easy to configure a Redux store. This function takes care of set..

middleware is a way to extend Redux with custom functionality. It is a function that sits between the action being dispatched and the action reaching the reducers. It allows you to intercept actions and do things like logging, routing, or asynchronous actions. Middleware is a composable function, which means that you can combine multiple middleware together. This makes it easy to add new functio..

Provider is a React component that makes the Redux store available to all of its child components. It is used to connect the Redux store to the React component tree. The syntax for using Provider is as follows: import { Provider } from 'react-redux'; const App = () => { const store = createStore(reducer); return ( ); }; In this example, the Provider component is used to make the store variable a..

CombineReducers is a Redux helper function that takes an object of reducers as input and returns a single reducer that combines the functionality of all the reducers in the object. This is useful when your application has a complex state that is managed by multiple reducers. The syntax for using CombineReducers is as follows: const rootReducer = combineReducers({ counter: counterReducer, todos: ..

Redux data flow is a unidirectional data flow architecture that ensures that data can only flow from the actions to the reducers, and then to the store. This makes it easier to reason about the state of the application and to track changes over time. The data flow in Redux is as follows: The user interacts with the application, which triggers a change in the state. The component that handles the..

Redux is an open-source JavaScript library for managing and centralizing application state. It is most commonly used with libraries such as React or Angular for building user interfaces. Similar to Facebook's Flux architecture, it was created by Dan Abramov and Andrew Clark. Redux follows a unidirectional data flow architecture, which means that data can only flow from the actions to the reducer..
