Interface DebounceOptions

If atBegin is false or unspecified, callback will only be executed delay milliseconds after the last debounced-function call. If atBegin is true, callback will be executed only at the first debounced-function call. (After the throttled-function has not been called for delay milliseconds, the internal counter is reset).

如果atBegin为false或未指定，回调函数仅在最后一次防抖函数调用后的delay毫秒执行。 如果atBegin为true，回调函数仅在第一次防抖函数调用时执行。 （在节流函数未被调用delay毫秒后，内部计数器将被重置）。
