How to convert JSOM response to simple object

Question

I'm using some javascript code to retrieve the workflow definitions on my site:

var context = SP.ClientContext.get_current();
var web = _context.get_web();
var serviceManager = SP.WorkflowServices.WorkflowServicesManager.newObject(context, web);
var deploymentService = serviceManager.getWorkflowDeploymentService();
var definitions = deploymentService.enumerateDefinitions();

context.load(definitions);

return context.executeQuery()
         .then(function(){
             console.log(definitions);
             var enumDefs = definitions.getEnumerator();

             while(enumDefs.moveNext()){
             ....
         });

BTW I've wrapped executeQueryAsync with jQuery Deferred so my JSOM code can resemble my REST code. Here is a John Liu's blog on how to do that.

This is working and I can clunkily iterate my way through the list. But I really, really dislike using the SP complex types and all their methods.

In the browser I see that a nice simple json array is being send back as the response. Is there anyway I can just get that?

Is there some way to easily change all the information that comes back into a json object?

You can use a next code to get simple objects

return context.executeQuery()
     .then(function(){
         return definitions.get_data().map(function(item) {
           return item.get_objectData().get_properties();
         });
     });
