         //Players names will be displayed in ascending order.
         var Players = [
            {player: 'Ronaldo',id: '12'},
            {player: 'Pele',id: '32'},
            {player: 'Neymar',id:'18'}
          ];

          //'myteam' is a collection instance and model 'Player' is specified using model property
          var myteam = new Backbone.Collection(Players,{
             model:Player,

             //The comparator method is used to maintain the collection in sorted order
             comparator: 'player'
          });

          //display the sorted records, records are sorted based on player as we have set comparator to 'player'
          document.write("The sorted items are: ",JSON.stringify(myteam.toJSON()));
