How to insert an element in object of an array

Question

Giving the following response:

response=[{"long":"long_value1","lat":"lat_value1","ts":"ts_value"},{"long":"long_value2","lat":"lat_value2","ts":"ts_value"},{"long":"long_value3","lat":"lat_value3","ts":"ts_value"},{"long":"long_value4","lat":"lat_value4","ts":"ts_value"}]

Then Using an api, I tried next step to do this operation in order to insert "address" property in response:

    for(var i in response){
      $http.get(url(i)).success(function(response2){
        response[i].address = response2.valueToassign;        
                });
}

My problem is that the "address" property is inserted only in the last object like this:

 response=[{"long":"long_value1","lat":"lat_value1","ts":"ts_value"},{"long":"long_value2","lat":"lat_value2","ts":"ts_value"},{"long":"long_value3","lat":"lat_value3","ts":"ts_value"},{"long":"long_value4","lat":"lat_value4","ts":"ts_value", "address":"address_value4}]

How does this loop could insert "address" in each object of the array?

Look up async loops. Also, for ... in should not be used on arrays. — Shilly

The problem with your code is that it is async,before loop executes
Try This

        var responses = [{"long":"long_value1","lat":"lat_value1","ts":"ts_value"},{"long":"long_value2","lat":"lat_value2","ts":"ts_value"},{"long":"long_value3","lat":"lat_value3","ts":"ts_value"},{"long":"long_value4","lat":"lat_value4","ts":"ts_value"}]

            function uploader(i){
            if(i< responses.length)
            {
            $http.get(url).success(function(response2){
                           if(response2){
                    response[i].address = response2.valueToassign; 
                  uploader(i+1) 
    }
    else{
         alert('resposnse output is blank');
         uploader(i+1)
      }    
 });

            }
            else{
            console.log(response);
            }
            }
            uploader(0)

I'm assuming you're trying to do this with recursion?

Yes Because your loop execute before your call is successed,Check my updated answer
