Arrays are like standard JavaScript arrays. a bag of elements that can grow or shrink.

Tuples, on the other hand, are fixed in length and type. They know exactly how many elements they contain and the specific types of elements at each position.

By the way, here’s the usual way to get the last element of a tuple:

Here’s what’s happening in this code: we’ve created a tuple that’s one element longer than the original T. Now, the length of the original tuple (T["length"] == 4) becomes our index, pointing to the last element of the newly created tuple.

I imagine you saying the same thing about bsky

Yeah, today’s challenge is much easier. 16 was tough, and the incorrect tests made it worse, I spent almost three hours trying to make it work.

even with the help of all LLM's I'm not able to pass test 4

15 was hard, tbh. I got to the final solution through brute force only.
