Sure, but one might argue that

Person("Dave", age = 30)

is also resolvable at compile-time. Is there anything else that requires

const

?

One would be wrong

Of course, I was just arguing that Jake's explenation wasn't really intuitive for a beginner.

Person("Dave", age = 30)

could also invoke a

init

block, adding logic that can't be known at compile time, such as serialization, network requests, and GUI operations

Let's say for he purpopses of my argument there's

data class Person(val name: String, val age: Int)

right below it.

Yes, but this is still perfectly valid:

data class Person(val name: String, val age: Int) {
    init {
        println("Oops")
    }
}
