Simply: var is used when the value is going to change. val when it isn't (constant.) Personally, until you understand it, code everything val. The compiler will complain, when it must be var and you should change it. Since the IntArray class doesn't change, the following is fine. val arr = arrayOf(1, 2) arr[0] = 3
