As a now second day kotlin learner, I'm really loving this syntax and no C gurus yelling at me that you cant add ++ definitions to class enums

fun makeComChoice(): Int = (1..3).random()

if (input == -1 || input in 1..3) isValid = true

else throw NumberFormatException()

return if ((comChoice + 1) % 3 == playerChoice) 0

else if (comChoice == playerChoice) 1

else 2

when (winTieLoss) {

0 -> {

score++

println("You win!")

}

1 -> println("It's a tie.")

2 -> {

score--

println("You lose, oh no!")

}

}
