In index.php, the 3 battle types are hard-coded right in the HTML.
-

So what happens if we decide to add a fourth battle type to BattleManager?
-
0:17
No problem. Add a new constant, then update the battle method logic for whatever cool thing this new type does.

But surprise, if we forget to also add the new type to index.php then nobody’s going to be able to use it.

Really, I’d prefer BattleManager to be completely in charge of the battle types
-
0:39
so that it’s the only file I need to touch when something changes.
-

To do that, create a new function in BattleManager that will return all the types and their descriptions.
-
0:51
Call it public function getAllBattleTypesWithDescription.
-
0:58
Here return an array with the type as the key
-
1:01
and the description that should be used in the dropdown as the value.
