How React 18 Improves Application Performance

Comprehensive, well-illustrated article on React 18 and its impact on performance. Explains how Concurrent React works and its impact on metrics such as Total Blocking Time and Interaction to Next Paint. Also presents other new features such as the Transition API, React Server Components, Suspense and the new React cache.

Kuma UI

New CSS-in-JS library inspired by the DX offered by Chakra UI, and compatible with React Server Components. The library is based on a unique hybride method that combines the best of zero-runtime CSS-in-JS and traditional runtime solutions. We'll have to study all this, and see how this library stands up to Panda CSS from the Chakra team.
