Get Country Flag using ISO Country Code

I use Javascript and Python as the main languages for development but I am eager and faster to learn anything that would be put a solution on the table.
Wouldn’t it be nice to be able to easily convert a regular ISO 3166-1 alpha-2 country code to its respective Unicode emoji flag? Here we go...
'GB'.toUpperCase().replace(/./g, (char) => String.fromCodePoint(char.charCodeAt(0) + 127397));
This will turn “GB” into 🇬🇧 (if it displays 🇬🇧 instead of the British flag, your system does not support emoji flags yet).
You can now write a reusable function that every time you pass a country ISO Code, you get an emoji flag.
const countryToFlag = (isoCode) =>
isoCode
.toUpperCase()
.replace(/./g, (char) => String.fromCodePoint(char.charCodeAt(0) + 127397));
To convert from an emoji flag to the country code:
'🇩🇪.replace(/../g, cp => String.fromCharCode(cp.codePointAt(0)-127397) );
NOTE: This is not supported in IE 11
