Running Node.js Readline functions

Question

I am new to Node.js and I do not understand how the readline module works. Here is my code block:

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


readline.question(`What's your funny name?`, name => {
  console.log(`Hi ${name}!`);
  readline.close();
});

Note that this block of code comes from this location on SO: Node.js "readline" not working as intended

I am expecting that the call to readline.question will pause and wait for the user to respond but this does not happen. The program continues on without pausing for input.

I have also tried

      process.stdin.read()
      process.stdin.on("data", (data) => {
        myAnswers.push(data);
        askQuestions(questionNumber+1);
      })

Again, the code does not pause to allow the user to input some text.

Any assistance would be appreciated.

It works fine on my end, It asks for an input then log it to the terminal — Abdelellah Dandashi, Dec 23 '22 at 21:05

This is an example from the official Node.js docs, if you say your code doesn't work, maybe try it this way:

import * as readline from 'node:readline/promises';
import { stdin as input, stdout as output } from 'node:process';

const rl = readline.createInterface({ input, output });

const answer = await rl.question('What do you think of Node.js? ');

console.log(`Thank you for your valuable feedback: ${answer}`);

rl.close();
