Hi everyone!
Cyril and Matthieu from Theodo Apps here 👋, standing in for Seb to bring you the latest news from React and React Native!
The previous edition was last Friday, so this one will be a bit shorter than usual. We’re resuming the usual pace of one newsletter every week after the holidays.
The 2024 edition of JS rising stars is out, you can start by having a look at which libraries performed well on this flawed but still useful metric of GitHub starts. Spoiler: shadcn/ui gained the most stars (again). Sébastien commented the Tooling section.
