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

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

If you are using Create React App, create a production build of your project:

npm run build
