JavaScript anti-shake case study

principle

The principle of anti-shake is: you can trigger an event, but I must execute it n seconds after the event is triggered. If you trigger this event again within n seconds of an event being triggered, I will use the time of the new event as the basis and execute it n seconds later. In short, I will not execute until you trigger the event and no more events are triggered within n seconds.
