Answer
Suspense lets components wait for async resources with a fallback UI. It supports streaming and async rendering.
Quick Answer
Suspense lets components declare they're waiting for something (data, code) by throwing a Promise. React catches the throw, shows a fallback UI (like a spinner), and resumes rendering when the Promise resolves. This makes async loading declarative — you don't need loading state variables scattered through your code.
