I tried to be smart and make an array, but forgot syntax... then created one using for... then iterated this using a forEach, and by this point I knew I was going wrong and not only did I not do a one line FizzBuzz, but also blanked on the modulo, neglecting to compare against zero. My takeaway was I need to practice coding like this as whilst the interviewer was friendly and did nothing wrong, I placed myself under pressure and failed to perform.
