Hey guys, I tried to read this block of code (from kotlin docs) a few times but I can't understand 3 things.

1. Red part- why is there a semicolon there?
2. Blue part - how is the `parent` which is a `Person` type can just call the `children` variable as like this list is a part of it?
3. I am also not sure how a `Person` instance is passed to the constructor of a class which is `Person`

Source: <https://kotlinlang.org/docs/reference/classes.html>

1. mistake in the example
2. `children` is a member of `Person` and `parent` is a `Person`

Ohh got it
Thanks <@U114Z86N6>
What about 3? (I just edited the question)

it’s not a very well thought out example, don’t overthink it

the point is to show you that secondary constructors exist and what the syntax is

I think if you change `class Person {` to `class Person() {` it will make sense.

<@UCPH15U5U> how does that makes a difference?

<@UK0BH8CJZ> because then you could build a `Person` without needing a `Person` to seed it (which would need `Person`, which would need a `Person`...)
