Asynchronous function that delivers results from factory after processing

I am facing an issue with a service(factory) that relies on another service to fetch data. Here is a simplified version of the code:

factory('myFactory', function(anotherFactory) {

     var factoryObject = {};

     factoryObject.myMethod = () {

          var newObjectToReturn;

          // asynchronous call
          anotherFactory.get(id, function(data) {

              // process the data
              newObjectToReturn = data; 
          });

          return newObjectToReturn;
     }
   return factoryObject;
});

The problem arises due to the asynchronous nature of the call, resulting in factoryObject.myMethod() always returning undefined. This is because return newObjectToReturn is executed before the data is available. I am looking for a solution to bypass this limitation. Any suggestions?

retrieve the callback response data

createFactory('customFactory', function(extraFactory) {

 var customObject = {};

 customObject.customMethod = () {

      var modifiedObjectToRetrieve;

      // asynchronous request
      extraFactory.fetch(recordId, function(result) {

          // perform some manipulation
          modifiedObjectToRetrieve = result; 
      },function(answer){
           return modifiedObjectToRetrieve;
      });
 }

return customObject; });
