good!

They are required if you have multiple arguments or no arguments, in this case, it wasn't required but he put it anyway.

What are the brackets supposed to do?

Oh, i see. Thank you very much.

It's parsed as a block otherwise.

Good lord, look at that...

I read this message too late because I can not login CW these two day(myjinxin2015 is github username, can't login now). @nolan, callee.caller is used for catch user's code, if there are another methods to catching user's code?

Thanks a lot jhoffner.

At least I was able to solve this kata without the repeat method.

I haven't looked too deeply here but it seems like the arguments.callee.caller chain in the preloaded code is causing the problem. I think if you update that (chop off two callers) you should be good to upgrade. Let me know if that doesn't resolve it

Great job on the parsing btw, this is well done! :)

But how can we change the language version!?

It's grey! I can't switch to Node v6 unless you have a tip/tutorial to change the version manually? So maybe we have to ask to the Codewars devs but I don't have any answer from them...
