Elegant UI updates using Transition (React18)
summary
Shows that marking heavy list filtering as low priority with useTransition and wrapping the filter setState in startTransition keeps the input update urgent and the UI responsive. Demo filters a ~500-550 user list; typing stops jank and only the list update runs relaxedly while isPending flips true so a loading indicator appears. Concrete claim: separating urgent input state from non‑urgent list state reduces perceived lag and it demonstrably works on the demo.
