Angular Promises - Do Something on Both Success and Error

I have a service that returns a standard resolve or reject promise. In my controller, I currently have something like:

myService.myServiceFunction(id).then(function(data){
    // do something with data
    $scope.myServiceFunctionFinished = true;
}, function(data){
    // do some error handling with data
    $scope.myServiceFunctionFinished = true;
});

In the above, both the error and success responses will trigger $scope.myServiceFunctionFinished being assigned a true value.

Is there anyway to shorthand the above so I am not defining the same thing twice? I am looking for the equivalent of a finally block if the above code was a try catch statement. The variable assignment I showed above must happen after the server responds.

You could use .finally function which will called once promise resolve/rejected.

Code

myService.myServiceFunction(id).then(function(data){
    //do success code
}, function(data){
    //do error code    
}).finally(function(){
    //do some final stuff which wouldn't care about promise resolve/reject
    $scope.myServiceFunctionFinished = true;
});
