for (i in 1..5) print(i)
-> 12345

for (i in 5 downTo 1) print(i)
-> 54321

for (i in 3..6 step 2) print(i)

for (i in 'd'..'g') print (i)
-> defg

For loop kotlin

val array = arrayOf(1, 3, 9)
for (item in array) {
    //loops items
}
for (index in 0..array.size - 1) {
	//loops all indices
}
for (index in 0 untill array.size) {
    //loops all indices
}
for (index in array.indices) {
    //loops all indices (performs just as well as two examples above)
}
