Locales and Currency

Used for number formatting and the currency symbol:

//E.g. for Germany, prices would look like 123.456,78 €
const data = { locale: 'de-DE', currency: 'EUR'};

//E.g. for US, prices would look like $123,456.78
const data = { locale: 'en-US', currency: 'USD'};

Formatting and symbols are applied through the ECMAScript Internationalization API
