Can I use React CDN and Babel Standalone CDN for production? For my small project.

React CDN

<script src="https://unpkg.com/react@17/umd/react.production.min.js" crossorigin></script>
<script src="https://unpkg.com/react-dom@17/umd/react-dom.production.min.js" crossorigin></script>

Babel CDN

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