freeCodeCamp Intermediate Algorithm Scripting: Pig Latin

translatePigLatin.js

// 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.



// This is my solution:
function translatePigLatin(str) {

  let letters=str.match(/^[^aeiou\s]*/);
  if (letters != "") {
    str=str.replace(/^[^aeiou]*/,"");
    str=str.concat(letters,"ay");
  }
  else {
    str=str.concat("way");
  }
  return str;
}

// But found this super cool solution (but is "y" a vowel?):
function translatePigLatin(str) {
  return str
    .replace(/^([aeiouy])(.*)/, '$1$2way')
    .replace(/^([^aeiouy]+)(.*)/, '$2$1ay');
}
