thread(isDaemon = true) {

while(true) counter.gamesPlayed = 0

}

for (i in 1..1_000) {

counter.totalScore += Random().nextInt(100)

counter.gamesPlayed++

println(counter.average)

}

Soon enough, you'll receive ArithmeticException anyway. Our counter somehow becomes zero.

If you want your data classes to be immutable, be sure to specify all their properties as val (values), and not var (variables).

Immutable collections

I think that our junior developer learned their lesson. Instead, they produced this code, which is not very efficient, but which gets rid of those variables:

data class ScoreCollector(val scores: MutableList<Int> = mutableListOf())
