Explain UI feedback and implement immediate feedback for API calls
WHAT IT TESTS: Connecting Nielsen's system-status heuristic to frontend architecture. ANSWER OUTLINE: Define feedback as real-time state communication; describe optimistic UI or spinners resolving to success or error after the API call.
WHAT IT TESTS: Whether you can translate Nielsen's visibility of system status heuristic into production frontend decisions for asynchronous operations. ANSWER OUTLINE: First, frame feedback as communicating current system state within reasonable time; second, describe a pattern like optimistic UI, disabled buttons with spinners, or skeleton screens that render immediately, then transition to success, error, or rollback states after the API resolves.
