Conditional rendering in React
React interview exercise on Components & JSX, difficulty 1 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 OrderStatus with props `status` ("pending" | "shipped" | "delivered") and an optional `trackingUrl`. Pending renders <p className="pending">We are packing your order</p>; shipped renders <p className="shipped">On its way</p> plus <a className="track" href=…>Track it</a> only when there is a URL; delivered renders <p className="done">Delivered. Enjoy!</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.
