Introduce currency.ForCountryCode() for getting a country's currency

[mboudraa]

It would be very useful to expose a function like

fun currency.getCode(countryCode string) (string, error) 

it would allow to retrieve the currency used by default for a given country

That does sound useful.

We have the data available in https://github.com/unicode-org/cldr-json/blob/main/cldr-json/cldr-core/supplemental/currencyData.json, we could parse it into a currencyCountries / countryCurrencies of type map[string][string] that maps country codes to currency codes.

Yes that would be great. Also at the risk of being to demanding 😅, Having the ability to have the currency full name would be also extremely useful for building drop downs of available currencies for selection for example

yes I build a local map of country to currency map[string]string that would allow me to do something like

currencyCode := countryCurrency["CA"]
digits, err := currency.GetDigits(countryCode)

Not having to maintain that map would be fantastic.

If I can help in any way, let me know

This is covered in the README:

Currency names are not included because they are rarely shown, but need significant space. Instead, they can be fetched on the frontend via Intl.DisplayNames.
