When should you use web workers?

Web Workers are a powerful feature in JavaScript that allow you to run scripts in background threads. They enable the execution of computationally heavy tasks without blocking the main UI thread, ensuring a smoother user experience. Use Web Workers when you need to handle large data processing, execute complex calculations, or manage tasks such as image processing, data fetching, or real-time notifications.

// Example of how to use a Web Worker to perform heavy computations if (window.Worker) { const worker = new Worker('worker.js'); worker.onmessage = function(e) { console.log('Result from worker: ', e.data); }; worker.postMessage('Start heavy computation'); } else { console.log('Your browser does not support Web Workers.'); }
