Using a react-intl FormattedNumber component, we‘ll pass a Number and a few additional props in order to render the correct separator and currency symbols for different languages.
For example we have price data as such:
"price": {
"en-US": "16.19",
"es-ES": "15.09",
"fr-FR": "15.09"
},
We can use FormattedNumber to display the correct currency.
let locale = (navigator.languages && navigator.languages[0]) || navigator.language || navigator.userLanguage || ‘en-US‘; <p> <FormattedNumber style=‘currency‘ currency={locale === ‘en-US‘ ? ‘USD‘: ‘EUR‘} currencyDisplay=‘symbol‘ value={merchant.price[locale]} /> </p>
