Debounce vs throttle: what is the difference?
Try code in the playgroundUnderstand the concept
Debouncing and throttling control how frequently a function runs when events arrive repeatedly. Debouncing waits for a quiet period, while throttling limits execution frequency during continued activity. They reduce unnecessary work but introduce different delays and must match the user experience.
Important ideas
-
Debounce waits until events stop for a short time; useful for search input.
-
Throttle limits how often work runs; useful for scroll updates.
-
Clear timers when the related component or task ends.
-
A 300ms search debounce normally sends a request after the user pauses typing for that time.
-
A throttle can report scroll position periodically even while scrolling continues; leading and trailing behavior depends on its implementation.

Turn this concept into a clear answer.
- Debouncing reduces bursts after inactivity; throttling keeps a steady maximum rate during activity.
