Hello guys, Can any one please answer the following question https://discuss.kotlinlang.org/t/how-does-tolist-function-works/6905 🙏

public fun <T> Iterable<T>.toList(): List<T> {
    if (this is Collection) {
        return when (size) {
            0 -> emptyList()
            1 -> listOf(if (this is List) get(0) else iterator().next())
            else -> this.toMutableList()
        }
    }
    return this.toMutableList().optimizeReadOnlyList()
}

This way:)

@am we are not talking about

mutable

vs

immutable

lists. there are no real

ìmmutable

-lists in kotlin yet.

List

is a read-only view of a

MutableList

underneath

Hey @Andreas Sinz can you more simplify please

immutable means that an object cannot change at all. As you've found out,

toList()

creates a

mutableList

and returns an object that implements

List<T>

which has no methods on it to change the underlying

mutableList

, so its a read-only List

Ooh thanks it clears a little air, this will help me in future Thank You @Andreas Sinz
