Prefer multiple useState or useReducer for multi-field forms?
WHAT IT TESTS: Matching state structure to complexity. OUTLINE: Separate useState for simple fields; one object for coupled validation or batch resets; useReducer for complex logic. RED FLAG: Picking one pattern for all forms without discussing coupling.
WHAT IT TESTS: Whether you scale state management with form complexity rather than defaulting to one pattern. ANSWER OUTLINE: For simple independent fields, separate useState hooks keep code readable and avoid extra re-renders. When fields share validation or need batch resets, a single object co-locates logic. Use useReducer once updates become event-driven or interdependent, since it centralizes transition logic. RED FLAG: Answering with only one pattern or claiming useReducer is always better for performance without evidence.
