🚀 React for Absolute Beginners: What the Heck Is a Component?

👋 Welcome, Curious Coder!
So you’ve heard of React — that “cool frontend thing” all the developers talk about.
But what even is a component?

Let’s break it down in the simplest way possible 👇

---

🧱 Components Are Like LEGO Bricks

Think of your UI like a LEGO house:

• Each brick = a component
• Put them together to make walls, rooms, even the whole house!

👀 Real World Analogy: Netflix

Open Netflix (or imagine it). You see:

• A navigation bar at the top ✅
• A list of shows in rows ✅
• A card for each movie ✅

Each of those is a React component:

<Navbar />
<MovieList />
<MovieCard />

---

In React, a component is a reusable piece of UI — like a button, navbar, or profile card.

✨ Your First React Component

Here’s what a basic React component looks like:

function Hello() {
  return <h2>Hello, world! 🌍</h2>;
}

You just made your own UI element!

To use it inside your app:

function App() {
  return (
    <div>
      <Hello />
    </div>
  );
}

That’s called reusing a component. And it’s powerful!
