🔗 MapSets: A set that's secretly a map

What if a set could be more than just a collection of items? In the article, Bruce Tate sheds light on MapSet, revealing its hidden map structure and how it utilizes maps for efficient membership checks. He explains that MapSet allows for quick lookups like traditional maps, but provides set functionality where order doesn't matter and duplicates are ignored. Readers learn how to create sets, check for membership, and effectively manage expected behaviors when working with MapSet, all while emphasizing the importance of the underlying map data structure. By understanding these concepts, developers can choose better data structures for various scenarios, enhancing both performance and clarity in their Elixir applications.
