##
## Return value

Scala's `map.clear()` function is used to erase all of the map's elements (key-value pairs).

##
## Code

The code below shows how to use the `map.clear()` function in Scala.

import scala.collection.mutable.Map
object Main extends App {
  //creating map
  val map = scala.collection.mutable.Map(
    1 -> "Tom",
    2 -> "Alsvin",
    3 -> "Eddie"
  )

  //map containg key value pairs before clear
  println("The map elements before clear: " + map);

  //map after clear
  map.clear();
  println("The map elements after clear: " + map);

}
