📘 Introduction to React

React is a popular JavaScript library for building user interfaces.
It is mainly used for creating single-page applications and allows developers to build reusable UI components.
React uses a virtual DOM to efficiently update and render only the parts of the UI that change.
It follows a component-based architecture where each component manages its own state.
React also provides hooks, enabling developers to use state and other features without writing class components.
React supports JSX, a syntax that lets you write HTML-like code inside JavaScript.
It is maintained by Facebook and has a large community and ecosystem of tools and libraries.

🚀 Key Features of React

• Component-Based Architecture → Build reusable and modular UI components.
• Virtual DOM → Efficient updates for high performance.
• JSX → Write HTML-like code directly in JavaScript.
• One-Way Data Binding → Data flows from parent to child components, making apps predictable.
• Hooks → Use state and lifecycle features without class components.
• Declarative UI → React describes what the UI should look like, not how to change it.
• Ecosystem Support → Works well with Redux, React Router, Axios, and other libraries.
• Large Community → Lots of tutorials, packages, and support available.

Overall, React makes it easier to build interactive, high-performance, and scalable web applications.
