 Please note that `util.inspect()` is a synchronous method that is mainly
-intended as a debugging tool. It's maximum output length is limited to 128 MB
-and input values that result in output bigger than that will not be inspected
-fully. Such values can have a significant performance overhead that can block
-the event loop for a significant amount of time.
