Title
Body
Suppose I have two arrays: val ar1 = Array[String]("1", "2", "3") val ar2 = Array[String]("1", "2", "3", "4") Now for each element of ar1 , I want to first concatenate that element with the corresponding element of ar2 , and then print the result. One way to do would be something like: List.range(0, ar1.size).foreach(i => println(ar1(i)+ar2(i))) It would have been nicer if there was a foreach variant that would allow me to work directly with the indices of ar1 instead of first constructing the integer list. Perhaps there is a better way?
