Master React 19.2 Async Everywhere — Boost Performance

React 19.2 introduces comprehensive async capabilities including Suspense, the use hook, useTransition, and view transitions. The guide demonstrates migrating from traditional useEffect patterns to modern async patterns, showing how Suspense catches thrown promises to manage loading states, how useTransition enables action props for better UX, and how view transitions provide GPU-accelerated animations. Includes practical examples using TanStack Start and comparisons with TanStack Query as an alternative approach.
