Flash / Flex / ActionScript/Array/sortOn

sortOn( ) supports sort modifiers

   <source lang="java">

package{

 import flash.display.Sprite;
 
 public class Main extends Sprite{
   public function Main(){
       var cars:Array = new Array(  );
       cars.push({make: "H",    year: 1997, color: "maroon"});
       cars.push({make: "Chrysler", year: 2000, color: "beige"});
       cars.push({make: "Mercedes", year: 1985, color: "blue"});
       cars.push({make: "Fiat",     year: 1983, color: "gray"});
       
       cars.sortOn("year", Array.DESCENDING);
            
       for (var i:int = 0; i < cars.length; i++) {
         trace(cars[i].color + "\t" + 
               cars[i].year + "\t" + 
               cars[i].make);
       }

There are five such optional flags that you can pass to either sort() or sortOn():

       public function toString():String {
           return """ + title + "", " + author + " (" + year + ")";

The sortOn( ) can sort on more than one field

   <source lang="java">

package{

 import flash.display.Sprite;
 
 public class Main extends Sprite{
   public function Main(){
       var cars:Array = new Array(  );
       cars.push({make: "H",    year: 1997, color: "maroon"});
       cars.push({make: "Chrysler", year: 2000, color: "beige"});
       cars.push({make: "Mercedes", year: 1985, color: "blue"});
       cars.push({make: "Fiat",     year: 1983, color: "gray"});
            
       cars.sortOn(["year", "make"]);
            
       for (var i:int = 0; i < cars.length; i++) {
         trace(cars[i].color + "\t" + 
               cars[i].year + "\t" + 
               cars[i].make);
       }
       cars.sortOn(["make", "year"]);
            
       for (var i:int = 0; i < cars.length; i++) {
         trace(cars[i].color + "\t" + 
               cars[i].year + "\t" + 
               cars[i].make);
       }
   }
 }
