Challenge

This month's challenge is all about types. We want to implement a type called Last<T> which will give us the last value in the array as a type. Let's check the example:

type arr1 = ["a", "b", "c"];
type arr2 = [3, 2, 1];
 
type tail1 = Last<arr1>; // expected to be 'c'
type tail2 = Last<arr2>; // expected to be 1

This challenge is coming to you from my favourite places to test myself and solve some challenges.
