A variable declared using the val keyword can not be reassigned in the same way that a variable declared using the final keyword can't be To understand the meaning of having a constant pointer to non-constant data consider the following Scala snippet: val m = scala.collection.mutable.Map(1 -> "picard") m // res0: scala.collection.mutable.Map[Int,String] = HashMap(1 -> picard) Here the "pointer" val m is constant so we cannot re-assign it to point to something else like so However, a def is evaluated when it is called, whereas a val or var is evaluated when it is assigned.
