This example shows how we can initialize arrays in Kotlin:
import java.util.Arrays

fun main() {

    val nums = arrayOf(1, 2, 3, 4, 5)

    val nums2 = (3..12).toList().toTypedArray()

    val nums3 = IntArray(5, { i -> i * 2 + 3})
[1, 2, 3, 4, 5]
[3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
[3, 5, 7, 9, 11]
