Or this:

const pigIt = str => str.replace(/(\w)(\w+)/g, '$2$1ay');

You can do a very similar thing with array methods and rest operator:

function pig(sentence){
  return sentence
          .split(' ')
          .map(([f, ...rest]) => rest.join('') + f + 'ay')
          .join(' ')
}

Yeah with RegEx you can do it very easily but I feel like it makes the code less readable.

You might find it's simpler if you rearrange it slightly. :)

const latinifyWord = (word) =>
  word.match(/[A-z]/i)
    ? `${word.substr(1)}${word.substr(0,1)}ay`
    : word;

const pigIt = (str) =>
  str.split(' ').map(latinifyWord).join(' ');

Yep, that also works :)

Is it just me or does your RegEx not work? I mean what you have is this:

/[A-z]/i

And it's basically saying does my word have at least one letter in it? So it if you have a semicolon attached to the end of your word, it will not be ignored. I think what you meant was someting like this:

/^[A-z]+$/i

That is if you wanted to ignore words with characters altogether.

Although what I thought when I read the task was that you were meant to rearrange the letters and keep the punctuation marks at the end, if any.

AlbertoM • Sep 30 '20

Uhm, I think what the task meant with leave the punctuation marks untouched was in the case of them being alone, so if you have ! you don't want to end up with !ay. My solution would transform hello! to ello!hay which may be wrong, you are right. They should have had stricter tests and a better description on CodeWars lol, they have no test case for a punctuation mark attached to a string.

Please note .. this is not the complete rules for PigLatin ..

For words that begin with consonant sounds, the consonant before the initial vowel should be moved to the end of the word sequence and "ay" affixed. E.g "pig" = "igpay"
For words that begin with consonant clusters, the clusters should be moved to the end of the word sequence and "ay" affixed. E.g "glove" = "oveglay"
For words that begin with vowel sounds, simply add "way" to the end of the word. E.g "explain" = "explainway”
