🧱 What is a Component in React?

A component is a reusable piece of UI in React. You can combine multiple components to build a complete application

📘 Example:

function Greeting() {
  return <h1>Hello, Developer!</h1>;
}

You can use it like this:

<Greeting />

✨ Key Points:
• Components are reusable
• Help keep code organized and modular
• Can be functional or class components

React apps are basically a tree of components working together. 🚀
