## Description
<section id='description'>
Translate the provided string to pig latin.
<a href="http://en.wikipedia.org/wiki/Pig_Latin" target="_blank">Pig Latin</a> takes the first consonant (or consonant cluster) of an English word, moves it to the end of the word and suffixes an "ay".
If a word begins with a vowel you just add "way" to the end.
If a word does not contain a vowel, just add "ay" to the end.
Input strings are guaranteed to be English words in all lowercase.
Remember to use <a href='http://forum.freecodecamp.org/t/how-to-get-help-when-you-are-stuck/19514' target='_blank'>Read-Search-Ask</a> if you get stuck. Try to pair program. Write your own code.

## Solution

```js
function translatePigLatin(str) {
  if (isVowel(str.charAt(0))) return str + "way";
  var front = [];
  str = str.split('');
  while (str.length && !isVowel(str[0])) {
    front.push(str.shift());
  }
  return [].concat(str, front).join('') + 'ay';
}

function isVowel(c) {
  return ['a', 'e', 'i', 'o', 'u'].indexOf(c.toLowerCase()) !== -1;
}
```
