// get metadata for a specific currency code
const usd = lib.currency('USD');
// {
//   "symbol": "$",
//   "name": "US Dollar",
//   "symbolNative": "$",
//   "decimalDigits": 2,
//   "rounding": 0,
//   "code": "USD",
//   "namePlural": "US dollars"
// }

// get currency metadata by country code
const eur = lib.currency('FR');
// {
//   "symbol": "€",
//   "name": "Euro",
//   "symbolNative": "€",
//   "decimalDigits": 2,
//   "rounding": 0,

Why?

Most solutions available are super overkill, not distributed as packages (e.g. gist), and/or out of date.
