This is my simple code which just adds a question in a database and then get an id as the result and then tries to add questionId in all answer.questionId

var size = questions.length;

for(var i=0; i<size; i++){                  
    $http.post(url + "questions", questions[i]).success(function(result){
        questions[i].answers = questions[i].answers.map(function(answer){
            return answer.questionId = result;
        });
    });
}

But promise calls in the end of the loop, therefore, question[i] - undefined since i = size;

How to solve the problem ?

Java != JavaScript. (Not even a little bit.) – T.J. Crowder Dec 14 '16 at 16:18
I know, I just made a mistake (it happens to everyone). Thanks for the duplicate link – Denis Evseev Dec 15 '16 at 00:05
`it happens to everyone` - mainly java "programmers" :p – Jaromanda X Dec 15 '16 at 00:39
@T.J.Crowder - Java is 40% JavaScript – Jaromanda X Dec 15 '16 at 05:31
@JaromandaX: Surely it's the other way around. ;-) – T.J. Crowder Dec 15 '16 at 08:35
