Country Flags

Unicode allows flags to be displayed. Also, the ISO 3166-1 alpha-2 code determines a country with 2 letters. Can the two be combined? From FR to 🇫🇷.


In fact, there are a multitude of examples online. You just need to know. The following function converts the parameter ISO 3166-1 alpha-2 code into an emoji:

function getFlagEmoji(countryCode) {
  const codePoints = countryCode
    .map(char =>  127397 + char.charCodeAt());
  return String.fromCodePoint(...codePoints);

We can notice three things:

This solution keeps flag management logic light and simple, and there’s no need for additional code! No dependencies, no svgs.

The biggest flaw is the lack of Windows support 😳

But otherwise, it’s ok.. There are of course things to optimize right and left. For two characters and an emoji, it’s still good enough. Simple.
