In a recent blog post, Dorian Karter explores converting country codes to flag emojis within the Elixir programming language. Inspired by a JavaScript example, Karter demonstrates how to achieve this in Elixir using a series of functional transformations to convert the country code into uppercase characters, map each character to its corresponding regional indicator symbol letter, and ultimately combine them to form the flag emoji. Leveraging the standard Elixir library, Karter also highlights the use of doctests in ExUnit, which allows automatic testing of example code.
