Just tried out your code and it works.

i only added attack function, i think it should pass the submit tests, but maybe i missed something, i read the description for times and times. I still don't understand what should I do.

It means your code returns undefined (does it actually return something?) whereas it is expected to return "raider".

expected undefined to equal 'raider'
//////////
what's that means?

Our code has many similarities

me too, code for human mindset

what does \B means

cringe 😶

.

感谢新思路！

lesser variables !

oh man ,you use chars less than me!!!!

I added the 3 consecutive array elements into a list so i could use the count() function to find which one of them is only once in there :)

i don't understand your code what does 3 append actually do
