 The `util.inspect()` method returns a string representation of `object` that is
 intended for debugging. The output of `util.inspect` may change at any time
 and should not be depended upon programmatically. Additional `options` may be

 `util.inspect()` will use the constructor's name and/or `@@toStringTag` to make
 an identifiable tag for an inspected value.
