In this chapter, we have a topic about “Using Countable Ranges to Make an ArraySlice”

We have this code below

```auto
let upcomingPlayersSlice = players[1...2]
print(upcomingPlayersSlice[1], upcomingPlayersSlice[2])
// > "Bob Cindy\n"

```

But when I run it in a playground, I see the inferred type of **upcomingPlayersSlice** is `Array<String>.SubSequence`.

Then, I just created a simple variable, where I explicitly set the type of ArraySlice and checked if can I assign to this variable our subsequence, and it works!

`let arraySlice: ArraySlice = upcomingPlayersSlice`

I am a little bit confused here, just the book said that we will create an ArraySlice type, I see that it is Subsequence type, and I see that it can be assigned to ArraySlice. Please could somebody guide me in the correct way of thinking about it?
