React 16.6.0 introduced the Suspense API, enabling functional components to handle asynchronous data fetching without class components or lifecycle methods. Suspense suspends component rendering while data loads from a cache, displaying a fallback UI in the meantime. Using the experimental react-cache package with unstable_createResource, data can be fetched and cached so Suspense can read it synchronously. A full working example is provided comparing the classic class-based async pattern with the new Suspense-based functional approach, though the pattern is noted as not yet production-ready.
