format a number without putting decimals (something like that)

numberFormatter.js

let num = 24674
const formattedNum = num.toFixed(0).replace(/(\d)(?=(\d{3})+$)/g, "$1.") // if you want to use commas instead of dots, you can
                                                                        // replace the "$1." to "$1,"

console.log(formattedNum) // 24.674
