Using futures to count children with name

futureNames.scala

case class Node(name: String, children: List[Node])
 
def count(node: Node, name: String) = {
  if(node.children == null && node.name == name) future{1}
  else if(node.children == null) future{0}
  else if(node.name == name{
    future{
      1 + node.children.foldLeft(0)((total,child) => total + count(child,name))
    }
  }
  else{
    future{
      0 + node.children.foldLeft(0)((total,child) => total + count(child,name))
    }
  }
}
