useTransition is a React Hook for marking state updates as non-urgent transitions, allowing more urgent updates to be processed first. It is useful when an immediate interaction should stay responsive while heavier UI work catches up. section 7.1.5
Responsive spell-check controls
A spell-check button should respond immediately, while highlighting spelling errors in a document can trail by several render cycles. Treating the highlighting update as lower priority prevents the button from appearing unresponsive or processing repeated clicks unexpectedly. section 7.1.5
React provides useTransition alongside useDeferredValue as two ways to specify low-priority state updates. The detailed implementation and usage patterns require further reference. section 7.1.5
