Is there a possible way implementing Promise inside angular.foreach?

Question

 var sanitizedresult=[];
    angular.forEach(voteResult, function(value, key) {
      // console.log(value.poll_watcher_id);
      var param={
        id : value.candida         


        

Answer 1

var sanitizedresult=[];

var processVotes = function(voteResult,idx){
    var param={
        id : voteResult[idx].candidate_id
      }
  CandidateService.getCandidatInfo(param).then(function(success){

    // console.log(success);
    console.log(idx+"Thi is it");
    var row = {
                ballot_name: success,
                vote_count: voteResult[idx].count
              }
              console.log(row);
    sanitizedresult.push(row);
    if(idx < voteResult.length-1){
        processVotes(voteResult,idx+1);
    }
  },function(fail){
    console.log(fail);
    if(idx < voteResult.length-1){
        processVotes(voteResult,idx+1);
    }       
  });   
}
processVotes(voteResult,0);

console.log(sanitizedresult);

There are no errors but still the sanitizedresult is empty what will be the possible cause why the "sanitizedresult" is empty
