Simulate pulling data down from a pageable api where you don't know how many pages there are in your request without using any mutable variables to keep track of what page you are on.

pageable.scala

import scala.collection.mutable.Queue

object Page extends App {
    val apiData = Queue(1000,1000,1000,1000,1000,10)
  
    Stream.from(1).takeWhile(getPage(_).nonEmpty).foreach(_ => processData())
    
    def getPage(x: Int): Queue[Int] = { return apiData }

    def processData(){ println(apiData.dequeue()) }
}
