         * 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.

         * invoked on the trailing edge of the timeout only if the throttled function
         * is invoked more than once during the `wait` timeout.

         * If `wait` is `0` and `leading` is `false`, `func` invocation is deferred
