Now if person<\/code> doesn’t exist, name<\/code> becomes undefined<\/code> instead of throwing an error. That’s quite useful if you ask me. In a way, it makes for more resilient code, since there is less possibility of a script that entirely bombs out. But there are arguments that it actually makes for less resilient code, because instead of fixing the problem at the root level (bad data), you’re putting a band-aid on the problem. <\/p>\n\n\n\n
