node.js - Taking multiple command line input in Node js using readline by async

Question

I have an array of questions named ques. I wish to use the readline function of node.js to print those question one by one using a for loop and then store answers in another array answer. When done I need to exit using the close() function of readline. I am new to node so tried using async but this does not seem to be working for me. I know i can implement it as multiple callbacks but i wish to avoid it and use async. Can it be done?. Here is what I have tried.

const readline = require('readline');

const rl = readline.createInterface({
    input: process.stdin,
    output: process.stdout
});

var ques=["Enter name:","Enter pass:"];
var answer=[];

async function dbParams(callback){
    for(var i=0;i<2;i++){   
        rl.question(ques[i], async (ans) => {
            answer[i]= await ans;
        });
    
    if(i==3)    
        callback("done");
    
    }
    
    return await callback;
    
}

dbParams(function callback(){
    rl.close();
});
