More accurate question for the-walking-dead

[CrossEye]

Although the answer is still the same, the question asks about the "return of the following console.log". console.log doesn't return anything, so the answer is undefined, but without teaching the relevant lesson about delete.

Asking instead what is logged, as in other questions, doesn't introduce this ambiguity.

This question had actually been overhauled, but I think there's room for your improvement still if you want to rebase and make the change on the current code!
