Debounce

Delaying execution of a function until a specified quiet period has passed since the last time it was called — collapsing a burst of rapid calls into one.

Example: Waiting 300ms after the user stops typing before firing a search request, instead of querying on every keystroke.

In practice: Different from throttle — debounce waits for a pause; throttle fires at a fixed maximum rate regardless of pauses. Both prevent a function from running more often than is useful.
