Mapping from one thing to another in Scala

I have been playing with Scala map functionality :O)

scala> val myList = List(1,2,3,4,5) myList: List[Int] = List(1, 2, 3, 4, 5)

scala> myList.map(x => x+1) res3: List[Int] = List(2, 3, 4, 5, 6)

scala> myList.map {x => x+1} res4: List[Int] = List(2, 3, 4, 5, 6)

scala> myList map {x => x+1} res5: List[Int] = List(2, 3, 4, 5, 6)

scala> myList map {x => if (x==3) println(“hello”)} hello
