Answer
Debouncing: Trigger function after a delay of inactivity.
Throttling: Trigger function at fixed intervals.
Useful for scroll, resize, and search inputs.
Quick Answer
Debouncing: delay execution until after a quiet period — a search input only fires after the user stops typing for 300ms. Throttling: execute at most once per time interval — a scroll handler fires at most every 100ms. Debouncing collapses bursts into one call at the end; throttling limits the rate. Both prevent performance-killing event handler spam.
