use(promise) and Suspense in React
React interview exercise on React 19, difficulty 2 of 3. Solve it in the editor beside a worked example; the tests run the moment you do.
Write Profile({ promise }) that reads a { name, role } user from the promise with use() and renders <h2>{name}</h2><p className="role">{role}</p>, and ProfileCard({ load }) that calls load() ONCE per mount, keeps the promise, and renders Profile inside a Suspense with <p className="loading">Loading…</p> as fallback.
Each exercise pairs a worked example with a twin problem to solve in a real editor; the tests run the moment you do. Progress is saved in your browser, and in your account if you sign in.
