Pig Latin help needed javaScript

Tell us what’s happening:

Your code so far

function translatePigLatin(str) {
  var firstVowel = str.match(/[aeiou]/);
  var firstpost = str.indexOf(firstVowel);
  if(firstpost>0) {
    return str.slice(firstpost)+str.slice(0,firstpost)+'ay';

  return str+"way";

Link to the challenge:

If the word doesn’t have vowels, firstVowel will be null, firstpost will be -1 and it will go to the else statement, so it will have "way" added at the end. Instead you need to add "ay" at the end of a word without vowels

let me try thank you
