+#### Pig Latin
+
+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.
+
+Input strings are guaranteed to be English words in all lowercase.

+export function translatePigLatin(str) {

+        return "";
+    }
+
+    if (/^[aeiou]/.test(str)) {
+        return str + 'way';
+    }
+
+    let splitStr = str.split(/([aeiou].*)/)
+    return [splitStr[1], splitStr[0], 'ay'].join('');
