Localize a checkout UI extension

In this tutorial, you'll use JavaScript API functions to localize an extension that displays a customer's loyalty point balance. You'll localize the extension text, the number format of the loyalty points balance, and the monetary value of the points. You'll also provide translations for singular and plural values. You can use what you learn here to localize other extensions.
