How to save result mongoDB query to an array or list?

Question

My query

test.find({ "age" : "20" }, {"email": 1, "_id": 0}).toArray(function (err,data) {
          if (err) throw err;
          console.log(data);

and result after I run my query

[ { email: 'root@root.com' } ]

How can I save console.log(data); to an Array or list ? I tried .push(data) to save but not ok.

Answer 1

Create an empty object and then assign value to it

test.find({ "age" : "20" }, {"email": 1, "_id": 0}).toArray(function (err,data) {
      if (err) throw err;
      console.log(data);
var obj =[];
var obj = data;
