What happens when placeholder text doesn’t get replaced
Someone I used to work with once left a alert('W.A.N.K') in the codebase. This was in a fairly rarely occurring branch of code and made it all the way to production.I've taken that as a warning and never write anything I wouldn't be happy for a customer to see in logs, test-data, comments (although handfuls of sarcasm are still acceptable) or debugging code.
