React.js is a library for building user interfaces, while Redux is a state management library for JavaScript applications. Although they are not the same thing, web developers frequently combine React.js and Redux, particularly when creating complex apps. React.js: Also known as React, this JavaScript package is used to develop user interfaces. Facebook created it and continues to maintain it along with a group of independent developers and businesses. With the help of React.js's component-based architecture, developers may create reusable user interface (UI) components that independently maintain state and can be combined to construct complex user interfaces. React handles the rendering of UI components in response to changes in the application's state, concentrating on the "view" layer of the application. Redux: Redux, on the other hand, is a JavaScript state management library that can be used with React.js but is not restricted to it. Redux offers an immutable state structure with a predictable state container for managing an application's state. It allows centralized application state management, which makes it simpler to monitor modifications, troubleshoot programs, and preserve component consistency. Applications requiring complicated state management and data flow frequently use Redux.

React.js and React Redux are not the same, but they are often used together in web development. React.js : React.js, commonly referred to as React, is a JavaScript library for building user interfaces. It focuses on the component-based architecture, where UIs are composed of reusable and composable components. React manages the state of these components, but it doesn't offer a built-in solution for managing application-wide state. React Redux : React Redux is a library that integrates Redux with React.js applications. Redux is a separate library for managing application state, providing a centralized store and predictable state updates. React Redux acts as a bridge between Redux and React, allowing React components to access the Redux store and dispatch actions to update the state. In summary, React.js is the UI library responsible for building components and managing their local state, while React Redux is an extension that provides a mechanism for managing global application state using Redux within React.js applications. a simple example of using Redux with React.js to manage a counter: // Redux: Define actions const INCREMENT = 'INCREMENT'; const DECREMENT = 'DECREMENT'; // Redux: Define action creators const increment = () => ({ type: INCREMENT }); const decrement = () => ({ type: DECREMENT }); // Redux: Define reducer const counterReducer = (state = 0, action) => { switch (action.type) { case INCREMENT: return state + 1; case DECREMENT: return state - 1; default: return state; } }; // Redux: Create store const { createStore } = Redux; const store = createStore(counterReducer); // React: Counter component const Counter = ({ value, onIncrement, onDecrement }) => ( Counter: {value} Increment Decrement ); // React-Redux: Connect Redux store to React component const { Provider, connect } = ReactRedux; const mapStateToProps = state => ({ value: state }); const mapDispatchToProps = { onIncrement: increment, onDecrement: decrement }; const ConnectedCounter = connect(mapStateToProps, mapDispatchToProps)(Counter); // React: Render App const App = () => ( ); // React: Render to DOM ReactDOM.render( , document.getElementById('root'));
