On part 10, the hint states:
However, don’t I have to write a return value… like return dishes[randomIndex]; ???
yes, you do. But a hint is hint, that is something different then the full solution. The hint points you in the right direction.
return dishes[randomIndex];
wouldn’t this work? since randomIndex returns a number and dishes gives an array
yes, that should work. The hint only tells you that you need a return value, you still need to figure out what that needs to be. Otherwise it would just be the solution, not a hint.
