Introduction to React: What is React?

Create a Simple React Component

Write a functional React component that displays your name inside an <h2> tag.

Expected output: <h2>Your Name</h2> rendered on the page.

Hint: Use a function that returns JSX with an <h2> element.

Explain Virtual DOM Benefits

Write a short paragraph explaining how the virtual DOM improves UI performance.

Expected output: A clear explanation of virtual DOM diffing and selective updates.

Hint: Focus on how React updates the real DOM efficiently.

React is a JavaScript library for building user interfaces. It is used to create reusable UI components and efficiently update the DOM using a virtual DOM, enabling fast and dynamic web applications.

The virtual DOM is a lightweight in-memory representation of the real DOM. React uses it to detect changes and update only the necessary parts of the actual DOM, improving performance.

React components are independent, reusable pieces of UI that can be functional or class-based. They manage their own state and props and compose together to build complex interfaces.
