I want to separate my digits with a comma from right to left (digit grouping)

I use this code to separate my number with comma: jQuery(this).val((jQuery(this).val().replace(/(\d{3}(?!,))/g, "$1,")));

If your number is a string or number itself with no comma at all then You can simply use toLocaleString method to display commas between thousands

Demo:

let str1  = parseInt('1234').toLocaleString('en')
let str2  = parseInt('12345').toLocaleString('en')
let str3  = parseInt('123456').toLocaleString('en')

console.log(str1)
console.log(str2)
console.log(str3)

Did you try the following?

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

console.log(numberWithCommas(12345)); // Output: "12,345"
console.log(numberWithCommas(123456789)); // Output: "123,456,789"
