Array bug with classes?

[BioShrimpCoding]

I am trying to add the Object into my array, amountOfZombie, the object “Zom” should be able to be added. I dont understand the bug and could someone fix it please

@BioShrimpCoding you forgot to initialize the array. in javascript variables are initialized to undefined unless you assign them.

e.g.

let amountOfZombies: zombieKind[] = []
