Doesn’t that look better than your nested if/else statements stretching out to
the right, riding off into the sunset?
The ‘switch’ statement
Let’s change up the example, because while I love long-necked creatures
that primarily exist to feed lions, I could benefit from a change of imagery.
We’re creating a video game. The user presses a button on their keyboard.

---

If they pressed W, move the player forward.
Else if they pressed A, move the player left.
Else if they pressed S, move the player backward.
Else if they pressed D, move the player right.
Else if….
See? It’s like a multiple-choice test!
While we could continue this pattern of doing if/else if, else if, else if, else
if checks until our heart dies out, there’s an easier way; the switch
statement.
Well, maybe not easier. I personally find it a bit overrated and think it opens
you up to making mistakes but screw it, you should know it.
I’ll show you both. The way we’d do it with what we know so far:
