This means that `smush(1,2,3)` will result in a type error because `[2,3]` is not an array of strings.

But what about `1`? Why is `1` not included in the array?

Becasue the Smush() function takes two argument, and one is an array. So the 1 goes for the first argument which is “firstString”, and then the [2,3] is for the “…otherStrings”. This is how I interpret it!
