Worker threads allow you to run JavaScript operations in parallel, providing a way to execute CPU-intensive tasks without blocking the main thread. They are useful for tasks that require heavy computation, such as image processing or data analysis. Example of creating a worker thread:
const { Worker } = require('worker_threads');
const worker = new Worker('./worker.js');
worker.on('message', message => {
console.log(`Received from worker: ${message}`);
});
worker.postMessage('Start working');
