This is a project for development purposes only, it consists of 2 files only: index.html

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <title>React Calculator</title>
  </head>
  <body>

    <div id="root"></div>
    <!-- React CDN -->
    <script
      crossorigin
      src="https://unpkg.com/react@18/umd/react.development.js"
    ></script>
    <!-- ReactDOM CDN -->
    <script
      crossorigin
      src="https://unpkg.com/react-dom@18/umd/react-dom.development.js"
    ></script>

    <!-- App Component -->
    <script src="./app.js"></script>

  </body>
</html>

app.js

const App = () => {
  return (<h1>Hello, World!</h1>)
};

ReactDOM.render(<App />, document.getElementById('root'));

I got this error:

Uncaught SyntaxError: Unexpected token '<' (at app.js:2:11)

Can someone help me to see what is wrong?
