Debouncing vs Throttling
By the HireReadyAI team · 7 min read
When to debounce search input, when to throttle scroll handlers, and how to choose.
Debounce
Debounce waits until events stop for a quiet period, then runs once. Search-as-you-type and resize handlers often use debounce so you do not fire a request on every keypress.
Throttle
Throttle runs at most once per interval while events continue. Scroll position updates and mousemove sampling often use throttle to keep a steady cadence.
Which to choose
Want the final value after a burst? Debounce. Want periodic updates during a burst? Throttle. Mention leading/trailing edge options if you have implemented them.
