The answer
Throttle (or debounce with immediate=true). Throttle with 500ms ensures the action runs at most once per 500ms. Debounce with immediate=true runs on the first click and ignores subsequent clicks for 500ms.

More FAQs in When to Use Debounce vs Throttle
Debounce. Wait for the user to stop typing, then make the API call. This avoids calling the API on every keystroke. 300ms is a good delay.
Throttle. The user needs continuous feedback while scrolling. Debounce would delay the update until scrolling stops, which feels laggy. Throttle limits to once every 100ms.
Either. Debounce if you want to recalculate after resizing stops (simpler, one calculation). Throttle if you want to update during resizing (smoother feedback, but more calculations). Debounce is more common.
