The kata is good, but I think it should be an 8 kyu not a 7.
ranks cannot be changed, it's no use complaining about them ;-)
CoffeeScript: usage of map is not enforced.
good but 8 kyu not 7
CoffeeScript Translation Kumited! Please accept :D
It's already approved, so closing the suggestion.
No way in javascript to get something like python's
partial(operator.mul, 2)or(2).__pow__?This comment has been hidden.
Your solution must not modify the original array.
In general, unless you're specifically told to modify an array that was passed as an argument, you shouldn't.
I don't wan't to sound pretentious, but maybe it was too easy for the 7kyu level.

Feel free to translate it to Ruby after a decade :)
Aww... I was hoping this wouldn't use floats :(
So you could do some bit-shifting action? ;P
Exactly
/fistbump/
.test('pmubtsif'.reverse())
Testeruse in example fixture breaks the tests.Ouch. Thanks for the heads up. I thought it was ok to use since the kata editor didn't complain. Fixed now.
Yeah... the "example" test fixture isn't checked, unfortunately.
Now, the stub solution has a bug in it. The last
}is stuck at the end of a commented line.Fixed the bracket. Thanks.
Can't see the change yet, my end. Will check tomorrow and mark it as fixed if it makes it through. ;P
@wthit56: I can see the change. If you still can't see it, you'll probably have to click the "Reset" button at the bottom to reload the template code. :-)
Ah-- forgot about that button. Thanks, OZ. Marked as "ready".
The object
Testerdoes not exist for the example tests.That could probably be replaced with
Test.assertSimilar(output, expected), which will deeply compare values in an array.I switched to Test.assertSimilar() as you suggested. Thanks.
Great, works now! I'd fix that minor typo that @wthit56 pointed out, but it looks good to me.
