async setup and Suspense in Vue
Vue interview exercise on Patterns, difficulty 3 of 3. Solve it in the editor beside a worked example, or cold in Interview mode with the example hidden; the tests run the moment you do.
Write UserCard with a prop `load` (() => Promise<{ name, role }>) whose async setup awaits it and renders <div class="user"><b>name</b> <i>role</i></div>; and Profile with the same `load` prop, rendering UserCard inside <Suspense> with a #fallback of <p class="loading">Loading…</p>.
Each exercise pairs a worked example with a twin problem to solve in a real editor; the tests run the moment you do. Interview mode hides the example: solve it from memory, without the hint or the solution, and it counts as solved cold. Progress is saved in your browser, and in your account if you sign in.
