JavaScript React Basics First Steps in React Understanding JSX

code compiles but html elements are not displayed. something wrong with render?

Looking for debugging help! My code compiles but the page is blank.

I'm on Windows 10 and using Visual Studio Live Server. Ty in advance!

Here's my code:

app.js

const title = <h1>My First React Element!</h1>;
const desc = <p>I just learned how to create a React node and render it into the DOM.</p>;

const header = React.createElement(
    'header',
    null,
    title,
    desc
);

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

index.html

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

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

Hi cloud712, thanks for the share. Looks like the main problem was that your JS file wasn't hooking up with the HTML because of the following code on line 15 of the index.html file.

<script type="text/bable" src="./app.js"></script>

In the type attribute above, "babel" is misspelled. :smiley:

omg 🤦 thank you so much hahaha

Hi cloud712, I can't tell what's wrong by looking at those snippets. But if you share a workspace snapshot or a GitHub repo link, then I could run the code locally and perhaps be able to locate the problem and point you in the right direction. :smiley:
