Lol why is dis 6kyu? look like 8 or 7 to me :P

Well that should be cleaner in the kata description which leave the door open for both aprouches.
But on the other hand that's pretty irrelevant for what this Kata is trying to show us.

Just cause using memo is an uncessary use of memory to calc a fibonacci number :P

It is unecessary to test all numbers to number to know if it is prime. Can skip all even numbers and reduce to the square root, saves looooooooads of tests :P

Description is very laking for beginners

Very simple :) totally a 8 kyu.

this assumes that there should be exacly 1 occurrence of each number always. the kata description doesn't say that just that it needs to have all elements from 0 to 9.

Lol, bravo! so simple so right!
Yet one thing remains, if both words are the same they aren't Anagrams (i think) the test cases fail there, but that's an extra if, lol.

Math yo, at first i was like wtf does he want with this, but then... dooh :P

I don't get it, fails at 6th test (invisible one). Does it not follow the kata input rules?

I'm with you all the way, but the point of this Kata was a javascript function, which means the salt is there heck even the final hash is there!

Knowing the password is not necessary to gain acess most times, considering that to be true has proven to be a huge security failure in the past.

But all you say is true when things are done server side, and real obscurity is in place, then and only then, all this makes sense :)

What's the point off all this when the relevant part's of your final hash are plain on the javascript? :P
