Please see the issue I filed above on the Python translation.

I'm guessing Jake Hoffner (jhoffner) would have to figure it out. I don't see any reference to a translation in the Kata Editor, and I don't see anything on your profile for published kata.

You're right, _sort will be called every iteration, so you can try to sort array2 outside the loop for a better performance (see bellow). Or you have another vision for completing this task?

function comp(array1, array2){
function _sort(arr) { return arr.sort(function(a,b) { return a-b; }); }
array2 = _sort(array2);
return !array1 || !array2 ? false : _sort(array1).every(function(elm,i) {
return elm === Math.sqrt(array2[i]);
});
}

I'm not seeing it for some reason.

I'll try it out now!

The problem doesn't make sense if, from the start, we have window height >= building height... so return -1 because we return, in normal cases an int. Otherwise we could have return nil/null/None .../Nonsense!

You should specify what is the desired behavior when duplicates exist in any of the three arrays. My solution passes with 50% probability... :-) I'm definitely not trying anything more efficient than this, until this issue is fixed.

Guess someone should probably add a test for that, huh?

Defining functions on prototype is usually a better idea: http://stackoverflow.com/questions/4508313/advantages-of-using-prototype-vs-defining-methods-straight-in-the-constructor

Nope @arichidoru, in fact it's even clearer the way you've put it. []s

Yes, that's the point the kata wants to teach.
