I was curious what the contents of React 18 were likely to be, so I read a few suggested articles, and here is another plain language breakdown to try to help clarify.
React 18:
- Not much new official information since June
- As a reaction to feedback to React 16 concurrency plans, a more turnkey update with individual concurrency architectural improvements instead of concurrency "mode"
- Change of the root API in App.tsx to allow piecemeal upgrades of react versions
- Performance: batching of state updates
- Performance: Optimizations to speed for Server Side Rendering
- usage API mostly stays the same
- ordering in sequence so things show up in sequence after lazy loading
- (mostly better useEffect debugging, maybe comes for free with react dev server)
- Likely low-difficulty to upgrade from React 17 to React 18 again.
