• [4217] Currencies
• [639-1] Languages

Installation

It can be installed in whichever way you prefer, but I recommend NPM:

npm install @ferranblanche/standards

Countries

Import de Countries module:

import { Countries } from "@ferranblanche/standards";
const countries = new Countries();

// false

countries.contains("xx");
// false

Get Country by code
