Use the format
getter function for formatting a single currency value, here for Russia:
var options = { style: 'currency', currency: 'RUB' };
var numberFormat = new Intl.NumberFormat('ru-RU', options);
console.log(numberFormat.format(654321.987));

Usando format
con map
Use the format
getter function for formatting all numbers in an array. Note that the function is bound to the NumberFormat

.
var a = [123456.789, 987654.321, 456789.123];
var numberFormat = new Intl.NumberFormat('es-ES');
var formatted = a.map(numberFormat.format);
console.log(formatted.join('; '));
// → "123.456,789; 987.654,321; 456.789,123"
