lmao. TDD all the way.

Very true!

sort mutates the original array so spreading here creates a new reference and avoids mutation. Not necessary in the exercise, true, but still worth using in a real application

[...arr] no need for this spread lol. arr is already an array

That probably means moderators remvoed their honor points for doing it.

Ooh, so if they get caught and have honor removed, their submissions aren't removed from history. That would explain it then haha

Part of them probably did. You can notice many of them have 8kyu ranking. That probably means moderators remvoed their honor points for doing it. Others could just copy the solution and test it after solving regularly the kata, which is fair.

You didn't have to abbreviate the variable names lol.

Interesting that all the variations submitted also have identically abbreviated variable names. Hmmm... wonder what that means.. People wouldn't look up the top voted answer on the internet then solve it by copying and pasting would they?? :P

WOOPS! In my brain I had converted the input to array already haha. Thank you

Not a kata issue, which data type is iterable there? Print the input.

I'm not sure if this has since been resolved, but as far as I could tell, the reason is that there is no input that required forcing anything to lowercase. I passed only by ensuring the first character of each word was capitalized.

To reiterate, it's not that the tests require it, it's that the test inputs don't have any uppercase letters embedded in the words anyway. So the problem requirements are accurate.
