To format a number with thousands separated by apostrophes, you can use a regular expression or the toLocaleString method with a custom locale. An example with a regular expression:

function formatPrice(price) {
  return price.toString().replace(/\B(?=(\d{3})+(?!\d))/g, "'");
}

console.log(formatPrice(12345678)); // "12'345'678"

Here, \B is a position not at a word boundary, (?=(\d{3})+(?!\d)) looks ahead for groups of three digits, not reaching the end of the string, and inserts apostrophes between them.
