You want to use the Number.toLocaleString function, therefore you need to make sure that you are calling it on a number and not on a string. See example below:

var n = 5555;
//var n=number.toString(); remove this line
var obj={
    style:'currency',
    currency:'GBP'
}

formatted = n.toLocaleString('en-GB', { style: 'currency', currency: 'GBP' });
console.log("formatted",formatted);
