Node.js - Worker Threads

You want to receive multiple results from a worker that sends messages repeatedly. Which approach correctly handles this in Node.js?

const { Worker } = require('worker_threads');
const worker = new Worker('./worker.js');
// What should you do here to receive all messages?

AUse worker.on('message', (msg) => { console.log(msg); }); to listen continuously

BCall worker.once('message', (msg) => { console.log(msg); }); to listen once

CUse a loop to call worker.postMessage repeatedly

DUse setTimeout to poll worker for messages

Step-by-Step Solution

Solution:

Step 1: Understand event listeners for multiple messages
Using worker.on('message') listens continuously for all messages sent by the worker.
Step 2: Compare with other options
once listens only once, loops or polling are unnecessary and inefficient for receiving messages.
Final Answer:
Use worker.on('message', (msg) => { console.log(msg); }); to listen continuously -> Option A
Quick Check:
Continuous message listening = A [OK]

Quick Trick: Use worker.on('message') for all messages, not once or polling [OK]
