Answer
Throttling: Ensures function runs at most once per interval.
Debouncing: Delays execution until activity has stopped.
Used to optimize scroll, resize, and input-heavy interactions.
Quick Answer
Throttle: limits how often a function fires — useful for scroll and resize events. Debounce: delays execution until after the last call — useful for search inputs. For async events: throttle rate-limits API calls triggered by user actions; debounce waits for the user to stop typing before making the API call. Both dramatically reduce unnecessary work.
