                    You didn't create an instance here, just an object literal. For oop, use either of there: https://jsfiddle.net/khrismuc/6ocatj0v/ – May 12 '20 at 08:37

                    Because the call that's responsible for determining the `this` context is `test();`, not `group.showgroup()` – Bergi May 12 '20 at 08:38
