Challenge 20 join() not working


Cannot use the join() method for some reason …
message.join(); in any case should work right ?


Without seeing your code, I can only give you very generic idea of what’s wrong with it, but many people encountered errors by trying to do a join on a string, which resulted in an invalid function… Could be that… :sunny:


Possibly. I didn’t want to give too much away on the last challenge. I did figure out a way around it thanks.

Is it possible you’ve omited the "" argument? I do not know what the default behaviour of the method is, but it’s been suggested participants call it this way: someArray.join("");
