Isn't it too easy for 6 kyu?

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?

Fixed the typo.

Fixed the typo.

Fixed.

Fixed the typo.

Oh, I didnt notice. Fixed!

As noted below, there is a typo in the description that should be fixed.

Yes, you need to fix the bug in your solution.

expected 'Destory all humans!' to equal 'Destroy all humans!'

JS: No random test

Cylons should have a model

It is not clear what model is.

return the string "Destory all humans!"

Should be "Destroy all humans!".
