According to http://stackoverflow.com/a/25352300/2928562 String.charCodeAt() performs better than a regular expression..

Like I said, I tested "ya" and it returns "ayay", thus my confusion. I checked specifically for "ya" as well to see if it was the issue and it didn't work, so I'm guessing "ya" is not the test case. I can't figure out what's going on.

Added in description that y is not a vowel :)

the y must go after the "a" because is a consonant and you must add after this "ay" so the solution is "ayay".

Thanks

Thanks! It was not clear for me first time.

Test's tests are those that you can see for exercising.
Submit's tests are others tests that you can't see for passing the Kata.

I have a technical problem with the Java version. I did this kata, all test were passed, but when I submitted it, I get the following message:
testtes3t5(TestPigLatin)
expected: but was:
test123(TestPigLatin)
0 Passed
1 Failed
0 Errors
I have a feeling, that in this kata the test classes are different in testing and in submission. In real test class there are no testtes3t5 test123 methods.
