Format INR currency using JavaScript (Part 2)

Some time back I had written about formatting INR currency using JavaScript. There I had shown a way using a regular expression. But we have come along since then and browsers now have better internationalization (i18n) support thanks to the introduction of Intl Object. Intl is a global object that provides many language sensitive utility functions.

Today we will be taking a look at Intl.NumberFormat(), which enables language sensitive number formatting.

const numberFormatter = new Intl.NumberFormat('en-IN', {
	style: 'currency',
	currency: 'INR',
	minimumIntegerDigits: 2,
	currencyDisplay: 'symbol',
});

function formatNumberToINR(num) {
	return numberFormatter.format(num);
}

const formattedString = formatNumberToINR(1234567.89);

console.log(formattedString); // ₹12,34,567.89;

The above example shows how to format numbers to INR currency but you can customise it your needs by passing appropriate options.
