every wait milliseconds. The throttled function comes with a Throttle.cancel
method to cancel delayed func invocations and a Throttle.flush method to
immediately invoke them. Provide leading and/or trailing to indicate
whether func should be invoked on the leading and/or trailing edge of the wait timeout.
The func is invoked with the last arguments provided to the
throttled function. Subsequent calls to the throttled function return the
result of the last func invocation.
