Pig Latin help request

Tell us what’s happening:

Your code so far

function translatePigLatin(str) {
  if (str[0]=="a"||"e"||"i"||"o"||"u"){
    return str + "way";
  }else {
    let firstChar = str.slice(0,0);
    return str + firstChar + "ay";

Link to the challenge:

please, write something in "tell us what’s happening " otherwise you are asking us to divine what you want

anyway, I will take a guess and say that

this is not doing what you want.
check again how the || OR operator works

Its easier and better to use regex in my opinion
