  **Your code so far**

function translatePigLatin(str) {
return str
.replace(/^[aeiou]\w*/ , '$&way')
.replace(/(^[^aeiou]+)(\w*)/, '$2$1ay')
}

console.log(translatePigLatin("shwartz"));

$1 refers to the 1st capture group represented by (^[^aeiou]+) and $2 refers to the 2nd capture group represented by (\w*). So whatever gets matched in those respective capture groups is used in the replacement value '$2$1ay'
