Call back function is not working node.js - node.js

Question

I am trying to build login system using node.js and i am stuck in this call back function error i have managed to build get login info and check them with data base but when i am verifying password it's taking some time so in there i need to use call back function but even i used callback function it's giving me the same error which is since validation or database call taking time it's executing other stuff in the in my case if conditions.
i have tried to implement this another way just tried to console.log order and all executing opposite this my result first
this is the order that it's run
3
2
undefined
1
but i need run this exactly opposite should i use promises instead of callback?
const {ipcMain} = require('electron');
const Password = require("node-php-password");
const connection = require("./connection");
var hash;
var done;
var self = module.exports = {
getuser_information:function(user_name,pwd,callback){
connection.query("SELECT * FROM `super_admin` WHERE ad_un = ?", user_name, function(err, result, fildes) {
if (err) throw err;
let numbers_retuned = result.length;
hash = result[0].desk;
console.log(1);
});
callback(hash,self.true_or_not);
},
hashverif:function(hash,true_or_not){
true_or_not();
console.log(2);
},
true_or_not:function(){
console.log(3);
return 1
}
}

UPDATE after your comment
You have two errors
Your get_stored_password function returns nothing when your callback function is called that's why console.log(function_returning_nothing()) outputs undefined
You forgot to pass done to your callback function in
get_stored_password's definition callback(done)
const {
ipcMain
} = require('electron');
const Password = require("node-php-password");
const connection = require("./connection");
var hash;
var done;
var self = module.exports = {
get_stored_password: function(name, pwd, callback) {
connection.query("SELECT * FROM `super_admin` WHERE ad_un = ?", name, function(err, result, fildes) {
if (err) throw err;
let numbers_retuned = result.length;
hash = result[0].desk;
if (numbers_retuned == 1) {
var test = pwd;
done = Password.verify(test, hash);
} else {
console.log('no');
return 0;
}
//you must pass an argument to your callback function
// and return done var to get an output when you log this function
callback(done);
return done;
});
},
chek_if_true: function(done) {
console.log(done);
if (done) {
return true;
} else {
return false;
}
}
}
That's why when you log done to the console it's undefined
