Flash / Flex / ActionScript/Array/unshift

Arrays can call unshift() to add any number of elements to the front of the array just like push().

   <source lang="java">

package{

 import flash.display.Sprite;
 
 public class Main extends Sprite{
   public function Main(){
       var queue:Array = new Array();
       queue.push("A");
       queue.push("J");
       queue.push("W");
       queue.unshift("J", "D");
       trace(queue); // Displays: Jim,Doro,James,Will
   }
 }

}

       </source>
   
  

Prepending Elements to the Beginning of an Array: the unshift() method

   <source lang="java">

package{

 import flash.display.Sprite;
 
 public class Main extends Sprite{
   public function Main(){
       var aEmployees:Array = ["A", "P", "C", "H"];
       aEmployees.unshift("R", "H", "L");
       trace(aEmployees.toString());
   }
 }

}

       </source>
   
  

unshift( )method adds one or more elements to the beginning of the array: theArray.unshift(item1, item2,...itemn);

   <source lang="java">

package{

 import flash.display.Sprite;
 
 public class Main extends Sprite{
   public function Main(){
       var versions:Array = new Array(  );
       versions[0] = 6;
       versions.unshift(5);      // versions is now [5, 6]
       versions.unshift(2,3,4);  // versions is now [2, 3, 4, 5, 6]
       
       trace(versions); // 2,3,4,5,6
   }
 }

}
