Implementing a debounced search input with useRef

Scenario

Context A search input triggers an API call on every keystroke, flooding the backend with hundreds of requests per second. The Problem The onChange handler calls the API directly without any delay mechanism, causing performance and cost issues. Constraints Implement debouncing using useRef to hold the timer reference. Wait 400ms after the last keystroke before firing the API call. Cancel the pending timer on each new keystroke. Expected Deliverable A React search input component implementing debounce with useRef and useEffect, reducing API calls to fire only after the user stops typing.
