Answer
The use hook unwraps promises directly during rendering and pauses rendering until resolved, working in server components.
Quick Answer
The use hook in React 19 is a new primitive that reads the value from a Promise or Context inside components (including conditionally inside loops). Unlike await which blocks, use integrates with Suspense — the component suspends while waiting, and resumes when the Promise resolves. Works in both Server and Client Components.
