If your attack wont defeat the titan there is no shame in running and you should "Run!"

When the damage = 0 the expected result is "Run!" which is wrong and not mentioned anywhere.

Return the damage done and the action as an array in the form [damage,"Action"]

The expected formula is damage = defense - attack * power which is wrong and not mentioned anywhere.

Into the "Test Cases" block of the kata editor. You can see examples for your solved katas. So try: https://www.codewars.com/kata/ones-and-zeros/solutions/javascript, look at "Show Kata Test Cases" and you will see what other do;-)...

Where would I have to incoroprate this? In the examples section?

Full ack!

3 pts in hand ;-)
