06 Bornfire Pig Latin.js

/* Bonfire: Pig Latin
Difficulty: 2/5

Translate the provided string to pig latin.

Pig Latin 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.

Remember to use RSAP if you get stuck. Try to pair program. Write your own code.

    // Take the string from the first vowel to the last char
