Let's say we have these 2 values

1.230

That means in Italy one thousand and 230, if an American had to write that, would write

1,230

Currently using:

myValue.toLocaleString('it');

For US we should be using myValue.toLocaleString('en-US');

How would we detect the correct number format we should be displaying?

Do you want something like that?

myValue.toLocaleString(navigator.language)

You can use Intl.NumberFormat as

var number = 3500;

console.log(new Intl.NumberFormat().format(number));
