Can you create multiple services from one factory in Angular?

I have a service called tableService created using the code as follows:

app.factory('tableService', [function() {
   var data = some data;

   var foo = function (){
      //do something to data here
   };

   return {
      data: data,
      foo: foo
   }
}]);

I want to create another service that has the same properties as tableService so that I can use its functionality on a different set of data.

Is there anyway I can do something like

app.factory('tableService', 'secondService', [function() {


}]);

So that I don't have to repeat the code twice, one for each service?

You can use, a local object definition, create new instance from it by using a getInstance method.

 app.factory('tableService', [function() {
   var data = some data;

   MyService(){
       // code ...
       this.data = data;
   }

   MyService.prototype.foo = function(){
       // code ...
   }


   function getInstance(){
       return new MyService();
   }


   return {
      getInstance: getInstance,
   }
}]);

Creating instances :

var tableSericeA = tableService.getInstance();
var tableSericeB = tableService.getInstance();
