Tell us what’s happening:
I do not know where to start. I looked at the solutions because I have no clue whatsoever. how is ‘this’ set to the array? I tried reading the documentation, but MDN uses complicated jargon to explain anything decently. And not to mention how does the callback even work? it needs an item, but how can you find the value to pass in?
I understand how maps work but the internal logic boggles my mind.
