Should every input handler be debounced?
Short interview answer
No. Local controlled-input state should normally update immediately. Debounce expensive downstream effects such as network requests, validation, or filtering, and ensure assistive feedback is not delayed unreasonably.
Key takeaway
Explain the underlying mental model clearly, then support it with a concrete example and its trade-offs.
