Correct way to write loops for promise.

Question

How to correctly construct a loop to make sure the following promise call and the chained logger.log(res) runs synchronously through iterat

Answer 1

I'd make something like this:

var request = []
while(count<10){
   request.push(db.getUser(email).then(function(res) { return res; }));
   count++
};

Promise.all(request).then((dataAll)=>{
  for (var i = 0; i < dataAll.length; i++) {

      logger.log(dataAll[i]); 
  }  
});

in this way, dataAll is an ordered array of all element to log. And log operation will perform when all promises are done.
