Scala List for each

scala-list-for-each.markdown

Use foreach to iterate over a list

val fruits = List("banana", "orange", "strawberry", "apple", "pear")
fruits.foreach(fruit => println(fruit))

For simple operations you can just use an underscore instead of naming the argument:

val fruits = List("banana", "orange", "strawberry", "apple", "pear")
fruits.foreach(println(_))
