 # Debounce Event
 
-Debounces batched browser event callback execution until the last event within a given time period. The utility returns a key upon event/callback attachment which can be later used to attach multiple callbacks to the same debounced event batch by given element, event name, and timeout. Debounced event batches can be manually detached, or will detach automatically if the callback is specified to be executed only once.
+Debounces batched browser event callback execution until the last event within a given time period. The utility returns a key upon initial event attachment which can be later used to add multiple callbacks to the same debounced event batch by given element, event name, and timeout. Debounced event batches can be manually detached, or will detach automatically if the callback is specified to be executed only once and there are no other callbacks left in the event batch.
