Is React broken?

JavaScript
1

Hello. A while ago I was working on a pong game, and a chessboard generator, both using React. Both of these used to work back when <I made them, but now, it’s just outputting this error to the console:

Uncaught TypeError: ReactDOM.render is not a function

Chessboard:

Pong:

that method was deprecated in 2022, if you use a more recent version of React you need to use a different way, see the official documentation: React 19 Upgrade Guide – React
