Leading is whether it is executed immediately upon entry, and trailing is whether it is triggered again after the event is triggered. The principle is to use a timer. If the event is triggered again within a specified time, the last timer will be cleared, that is, the function will not be executed and a new timer will be reset until the function in the timer is triggered automatically after the specified time is exceeded.

At the same time, a cancel function is exposed through the closure, so that the external counter can be cleared directly.
