React is a JavaScript library used to build user interfaces (UI), especially for web applications.
It helps developers create interactive and dynamic websites.
It's Developed by Meta platform.
React is used to build fast, interactive, and reusable web interfaces using components.
Why we are using React:
1) Component-Based Architecture - React allows you to create small reusable components. Ex: Navbar, Button, Footer, Card.
2) Fast Performance (Virtual DOM) - React uses Virtual DOM, so it updates only the changed parts of the page instead of reloading the whole page.
3) Reusable Code - Components can be reused in many places, which reduces code repetition.
4) Easy State Management - React provides hooks like useState and useEffect to manage data and updates.
5) Single Page Applications (SPA) - React helps build fast single-page applications where pages update without full reload.
6) Large Community - Many developers use React, so there are many libraries, tutorials, and support available.
