How can I use map and receive an index as well in Scala?

Question

Is there any List/Sequence built-in that behaves like map and provides the element\'s index as well?

Answer 1

Use .map in .zipWithIndex

val myList = List("a", "b", "c")

myList.zipWithIndex.map { case (element, index) => 
   println(element, index) 
   s"${element}(${index})"
}

Result:

List("a(0)", "b(1)", "c(2)")
