REACT LABS: WHAT WE'VE BEEN WORKING ON – FEBRUARY 2024

Summary from the TLDR Web Dev newsletter

The React Compiler is now in production on Instagram. It automatically re-renders only the necessary parts of a UI upon state changes. The React team has been adding features to React Canary, which allows early adoption of stable features before official release, like Server Components and Actions. Actions in React can handle data submissions in both client-only and client-server apps and it offers features like optimistic updates and form state management.
