What are web workers and how do I use them?
Web workers are JavaScript scripts that run in the background, separate from the main thread. They help in performing tasks without blocking the user interface.
Can you give me an example of how to create a web worker?
Sure! You can create a web worker by using the Worker
constructor. For example: const myWorker = new Worker('worker.js');
This will run the script 'worker.js' in a separate thread.
What kind of tasks are suitable for web workers?
Web workers are great for tasks like data processing, image manipulation, or any computation-heavy operations that would otherwise freeze the UI.
Are there any limitations I should be aware of?
Yes, web workers have some limitations. They can't access the DOM directly, and they have a different scope, so you need to use message passing to communicate with the main thread.
