Answer
use unwraps promises directly inside components, eliminating useEffect + state boilerplate and improving SSR/RSC data workflows.
Quick Answer
The use hook in React 19 reads a Promise inline in the component body — React suspends if the Promise isn't resolved. Unlike useEffect, use works with Suspense automatically and can be called conditionally. It replaces the awkward useEffect + useState + loading state pattern for data fetching with a much cleaner syntax.
