This question is so confusing. I've literally no idea what you mean with the ctx. Are you refering to a global variable or something else? I know how to set the context of a function call but I don't understand the wording of your question.

I think the instructions on this one are pretty confusing. The main thing that held me up here was the instruction example: logOnce("foo") // -> "foo". This looks to me like that logOnce function should return the value "foo", but that's not actually what's expected.
