function translatePigLatin(str) {
var strArr = [];
var tmpChar;
// check if the char is consonant using RegEx
function isConsonant(char) {
return !/[aeiou]/.test(char);
}
// return initial str + "way" if it starts with vowel
// if not - convert str to array
if (!isConsonant(str.charAt(0)))
return str + "way";
else
strArr = str.split("");
// push all consonats to the end of the array
while (isConsonant(strArr[0])) {
tmpChar = strArr.shift();
strArr.push(tmpChar);
}
// convert array to string and concatenate "ay" at the end
return strArr.join("")+"ay";
return str.replace(/^[aeiou]\w*/, "$&way").replace(/(^[^aeiou]+)(\w*)/, "$2$1ay");

### Code Explanation:
* `isConsonant()` is used to check if a character is a consonant.
* If first character is vowel, add **way** to end of string and return it.
* If first character is not a vowel:
* Split string into array using `split()`.
* Push all consonants to end of array with help of `shift()` and `push()`.
* Convert array to string using `join()` and add **ay** to end of string. Return it.
* Use `replace()` on the string, using a regular expression to check if the first letter is a consonant and adding **way** at the end in this case. If the first letter is a consonant nothing will happen at this point.
* Use `replace()` again to check for consonants at the beginning of the word and to move it or them to the end of the word and add **ay** at the end.
