Convert raw string from api into currency format

Question

I'm using an api to get some product details that display on my WordPress page (total beginner in WordPress & JavaScript).

Response from api: 1234
What i need: 12.34€
Sometimes i get no data back --> no price available

What i came up with so far:

    $(".offer-price, .-list-price").text(function(index, text) {
      if (text.length == 0) {
        return ""
      } else {
        var digits = text.split("");
        var back = digits.slice(-2).join("");
        var front = digits.slice(0,-2).join("");
        return front + "." + back + "\u20AC";
      }
    });

This function solves my problem. Since i am trying to improve / learn i would love to get some feedback from you guys on my approach and alternative ways to solve the issue. I'm sure there are better ways to tackle this?!

Anyway it easer to do just by devision by 100 :) `Number(text)/100 + "\u20AC"` — zb', Mar 11 '17 at 17:50

you can Use regex

function format (num) {
return num
   .toFixed(2) // always two decimal digits
   .replace(".", ",") // replace decimal point character with ,
   .replace(/(\d)(?=(\d{3})+(?!\d))/g, "$1.") + " €" // use . as a separator

}
