I am 5Kyu in javascript. I am now writing katas in Ruby. But even after solving 5kyu kata in ruby twice my rank is still 7 and not going up. I have solved a different kata in ruby still the same.

Thank you for your suggestion. I have edited it and included more details. As well as I have included more basic and random tests.
To me it does not seem like a duplicate kata.

I am also getting same error. My program works everywhere else fine.
TypeError: Cannot read property 'sort' of undefined at testAnagrams at Object.handleError at ContextifyScript.Script.runInThisContext at Object.exports.runInThisContext

any suggestions please

I am going to improve it to include more tests. I am new to this site and don't know much about random testing. I appreciate your feedback. Any suggestions please let me know

how come (1212) is true ; it is not palindrome

Can anyone please help with this? i dont know why i am getting this. I am new to codewars and also how do you run tests?
