Nice list, but I disagree with the last topic. ๐๐ซ๐จ๐ฉ๐๐ฒ๐ฉ๐๐ฌ was deprecated, and his last release was 3 years ago. And also, react 19 ignores PropTypes (and defaultProps).
Super useful list, thanks for sharing! Will be sure to go through this checklist when developing my React apps. Just bookmarked this โ
