Why am I not seeing anything on screen?

I'm using the workspace and I have all the same code as what's in the exercise, but nothing is showing on screen. I'm not even getting console errors.

Here is my code in app.js:

const Header = () => {
  return (
      <span className="stats">Players: 1</span>

const Player = () => {
  return (
    <div className="player">
      <span className="player-name">

      <Counter />

const Counter = () => {
  return (
      <div className="counter">
        <button className="counter-action decrement"> - </button>
        <span className="counter-score"></span>
        <button className="counter-action increment"> + </button>

const App = () => {
  return (
    <div className="scoreboard">
      <Header />

      {/* Players list */}
      <Player />

  <App />,

And here's the code in index.html:

<!DOCTYPE html>
    <meta charset="utf-8">
    <link rel="stylesheet" href="./app.css" />

    <div id="root"></div>
    <script crossorigin src="https://unpkg.com/react@16/umd/react.development.js"></script>
    <script crossorigin src="https://unpkg.com/react-dom@16/umd/react-dom.development.js"></script>
    <script type="text/babel" src="./app.js"></script>

Does anyone know why nothing would be showing?

Thanks in advance!

Your html is missing a babel script just above the one for app.js

  <script src="https://unpkg.com/babel-standalone@6/babel.min.js"></script>
    <script type="text/babel" src="./app.js"></script>

Did you download the project files or launch workspace from the video?
