The document provides an overview of ReactJS, a popular JavaScript library for building user interfaces, highlighting its component-based architecture, virtual DOM, and performance benefits. It explains key concepts such as components, state and props, and the introduction of hooks for managing state in function-based components. Additionally, it mentions the use of Redux for state management in larger applications, emphasizing ReactJS as a suitable choice for modern web development.

- 3. INTRODUCTION TO REACTJS ReactJS is a popular JavaScript library used for building user interfaces. It was developed by Facebook and is now maintained by a community of developers. ReactJS allows developers to create reusable UI components that can be used across different applications. One of the key features of ReactJS is its virtual DOM. This allows ReactJS to update only the parts of the UI that have changed, rather than updating the entire UI. This results in faster performance and a better user experience.
- 4. COMPONENTS IN In ReactJS, components are the building blocks of the UI. Components can be thought of as functions that take in data as input and return UI elements as output. Components can be either class-based or function-based. REACTJS Class-based components in ReactJS are created using the ES6 class syntax. They have a state object which stores data that can change over time. Function- based components, on the other hand, are simpler and do not have a state object. They are commonly used for rendering static content.
- 5. STATE AND PROPS IN REACTJS State and props are two important concepts in ReactJS. State refers to the data that can change over time within a component. Props, on the other hand, are read-only and are passed down from a parent component to a child component. State can be updated using the setState() method in ReactJS. When the state of a component changes, ReactJS re-renders the component and updates the UI. Props are used to pass data and event handlers down to child components.
- 6. REACTJS HOOKS Hooks were introduced in ReactJS version 16.8. They allow developers to use state and other ReactJS features in function-based components. Prior to hooks, state could only be used in class- based components. There are several hooks available in ReactJS, including useState(), useEffect(), useContext(), and useRef(). These hooks allow developers to manage state, handle side effects, and access the ReactJS context and DOM.

It provides a centralized store for managing the state of an application. Redux can be used with both class-based and function-based components.
- 8. CONCLUSION ReactJS is a powerful JavaScript library used for building user interfaces. Its virtual DOM and component-based architecture make it fast and efficient. With the introduction of hooks, developers can now use state and other ReactJS features in function-based components. ReactJS can be used with other libraries and frameworks, such as Redux, to provide a scalable and predictable way of managing state in large applications. Overall, ReactJS is a great choice for building modern web applications.
