Question: You are doing code review and come across a javascript application that does not do input validation. Would you have the developer go back and write in input validation? If so, why? If not, why?
Where does the app run? If it's client-side, and there's no user-interface gains, I would leave it alone and settle for validating that any server-side component of the app is handling input validation. The reason being the obvious - that client-side input validation is trivially circumvented, so it's not worth my time or the developer's.
