 Huge thanks to the folks who volunteered their time to participate in the alpha and beta testing program. Your enthusiasm and invaluable feedback helped us shape these docs. A special shout out to our beta tester, [Debbie O'Brien](https://twitter.com/debs_obrien), who gave a talk about her experience using the React docs at React Conf 2021.
 
 Finally, thanks to the React community for being the inspiration behind this effort. You are the reason we do this, and we hope that the new docs will help you use React to build any user interface that you want.

 Using the original line index as a `key` doesn't work anymore because each separator and paragraph are now in the same array. However, you can give each of them a distinct key using a suffix, e.g. `key={i + '-text'}`.
