What are web workers

Web Workers are a feature of modern web browsers that allow you to run JavaScript scripts in background threads. This means that you can perform computationally intensive tasks without blocking the main thread, ensuring the user interface remains responsive. Web Workers are ideal for tasks like image processing, data synchronization, and handling large arrays or data sets.

Using Web Workers can significantly improve the performance of web applications, especially when dealing with heavy computations or real-time data processing tasks.

// Example of using web workers const worker = new Worker('worker.js'); worker.onmessage = function(event) { console.log('Message received from worker:', event.data); }; worker.postMessage('Start processing');
