What is Component means ?
The meaning of component is you say in simple language is react divide the code of website let say if we want to make a website and we want to use a code repeatly so we have to write the again and again but if you was use component you have to write code at ones and use it by import it again and again you can work very efficiently and fast

HTML -


<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>project</title>

</head>
<body>
<nav id="navbar">
<div id="logo">
<img src="img/B.png" alt="myonblinemeal.com">
</div>
<ul>
<li class="item"><a href="#">Home</a></li>
<li class="item"><a href="#">contact Us</a></li>
<li class="item"><a href="#">About</a></li>

<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Placeat minima fugiat ullam quasi adipisci eveniet. Soluta voluptates et quisquam earum voluptatibus veniam enim qui, voluptatum esse possimus pariatur eos magni.</p>
<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Placeat minima fugiat ullam quisquam earum voluptatibus veniam .</p>
<button type="submit" class="btn">Click</button>
</section>
</body>
</html>

JSX -

NOTE - In JSX we only use body of html 
\
<>
  <nav id="navbar">
    <div id="logo">
      <img src="img/B.png" alt="myonblinemeal.com" />
    </div>
    <ul>
      <li className="item"><a href="#">Home</a></li>
      <li className="item"><a href="#">contact Us</a></li>
      <li className="item"><a href="#">About</a></li>
      <li className="item"><a href="#">Serives</a></li>
      <li className="item"><a href="#">Blogs</a></li>
    </ul>
  </nav>
  <section id="home">
    <h1 className="h-primary">Welcome to Website </h1>
    <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Placeat minima fugiat ullam quasi adipisci eveniet. Soluta voluptates et quisquam earum voluptatibus veniam enim qui, voluptatum esse possimus pariatur eos magni.</p>
    <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Placeat minima fugiat ullam quisquam earum voluptatibus veniam .</p>
    <button type="submit" className="btn">Click</button>
  </section>
</>

after code you can see the deference of html and jsx so it is we end this react js study tour .
