Help for in or forEach Kotlin

Question

What is the difference and which is best between

fun main(args: Array<String>) {
var arr = arrayOf(1, 3, 5)
for (i in arr) {
println(i*4)
}
}

and

fun main(args: Array<String>) {
var arr = arrayOf(1, 3, 5)
arr.forEach {
println(it * 4)
}
}

Answer 1

In case if you want to traverse only the array. You can use both the loops(any one of it)

But usign for each u can neither use conditions like print odd numbers, nor you can reverse the array

Answer 2

In case use for each loop because it reduces the chances of errors
