Challenge: Basic JavaScript - Profile Lookup

Link to the challenge:

Return statements immediately stop the function, even inside of a loop.

Wow… so the issue was solved after I moved that return statement out of the loop. Thanks, Jeremy but why is the return “no such property” statement not causing any problems?

It’s guarded by an if statement to make sure it happens at the right time - only when you found a contact with a matching name.
