Pig Latin. A can't pass the test

I’m trying to pass tests.
Last test is “Should handle words without vowels.”

In this case my code takes a string without vowels and adds a “ay”.
What did I get wrong?

Your code so far


function translatePigLatin(str) {
  let myStr = str;
  myStr = myStr.replace(/^([bcdfghjklmnpqrstvxzw]+)(.*)/, "$2$1ay");
  myStr = (myStr == str)? myStr + "way" : myStr;
  return myStr;
}

translatePigLatin("qwrt");

Answer: Y - is consonant too.
So, i change “replace” pattern to [bcdfghjklmnpqrstvwxyz] and pass test.
