Intl API: Number Formatting

The _ between numbers are numeric separators, although they are unnecessary, I find large numbers more readable this way.

Table of contents

Views Counter

numbers-formatter.js
const viewsFormatter = Intl.NumberFormat("en", {
notation: "compact",
});
const views = viewsFormatter.format(1_722_012_999);
console.log(views); // 1.7M

Currency

currency-formatter.js
const currencyFormatter = Intl.NumberFormat("en", {
notation: "compact",
style: "currency",
currency: "USD",
});
const amount = currencyFormatter.format(5_210);
console.log(amount); // $5.2K
