ReactDOM.render has been deprecated since React 18. If you're running React 18 with ReactDOM.render, you should already see an error urging you to switch because essentially ReactDOM.render works in React 17 mode.

const root = createRoot(domNode) root.render(<Stuff />)

(or the JSX transform output equivalent)
