JavaScript - one reason to doesn't forgot the 'break'

First if isn't a acumulative thing, think sometimes you don't want to know if the person is fat, ugly or dumb, but if the person is fat ugly and dumb, but why doesn't forgot the break, is that if in the end you have an 'default' that could be firing you ask something that doesn't exist, and only would work if there isn't the case, without the break you can receive a message like Ok you buy mangos and I'am sorry you ask a fruit that we don't sell, imagine I don't ask if is fat, ugly and old but if is old, fat and ugly, essence... essence.
