Getting http-server to look in the correct folders

I'm just trying to build a react hello world app but can't seem to get it to work.

I cd to the correct directory then run 'http-server -p 3000' but it won't render the react element correctly. In dev tools it says "unexpected token '<' on line 2'. There's not a '<' anywhere in my app.js file so I'm guessing it's not looking in the correct directory.

I installed http-server globally, but like I said, I navigated to the directory that the files I'm working on are in.

This is all I've got in the directory;

React-ChessClock (directory)
---app.js
---index.html
---styles.css

<!--index.html file-->
 <!DOCTYPE html>
 <html lang="en">

  <head>
     <meta charset="UTF-8">
     <title>TITLE</title>
     <meta name="description" content="DESCRIPTION">
     <!-- <link rel="stylesheet" href="PATH"> -->
  </head>

  <body>
    <div id="root">Loading...</div>
  <script crossorigin src="https://unpkg.com/react@16/umd/react.production.min.js"></script>
  <script crossorigin src="https://unpkg.com/react-dom@16/umd/react-dom.production.min.js"></script>
  <script src="app.js"></script>
  </body>
 </html>

//app.js file
const header = React.createElement(
  'h1',
  null,
  "Hello React!"
);

ReactDOM.render(
  header,
  document.getElementById('root')
);

Anyone got any advice? lol

Dangit. Tried to change it to a component and now it's back to the 'unexpected token <' error.

function Header() {
  return (
    <div>
      <h1>5:00</h1>
    </div>
  );
}

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

Is my syntax incorrect somewhere?
