It's a great question! I really want to introduce more about these kinds of topics, as well as more concepts about Function Programming in the future advanced tutorial video. Just look forwarding to it :)
Hint: We can use extension, which we will introduce in season 4, to extend the ability of a existed class or struct, including Array, of course.?
