JSX class code not working

[nrudrawar]

Hello
JSX from the Core React Components class doesn't work, followed all the steps correctly. But the code with JSX doesn't work, I get the server running but only HTML is printed out. no CSS or logo etc is visible on the page.
I also got an error for index.html and it suggested to add type="module" to script tag

<script type="module" src="App.js"></script>

But doing that also it doesn't work

Update - looks like babel doesn't seem to be working in chrome on mac, as my code works in Safari but doesn't properly on chrome
