What are some use cases for JavaScript web workers?

JavaScript web workers are great for running scripts in background threads. They can be used for tasks like image processing, data fetching, and handling large computations without blocking the UI.

Can you give me an example of image processing with web workers?

Sure! You can use a web worker to apply filters to images. For instance, you can send an image to a worker, have it process the pixels, and then return the modified image back to the main thread.

What about handling large datasets?

Web workers can parse and process large JSON files or perform complex calculations on datasets without freezing the user interface, making the application more responsive.

Are there any limitations to using web workers?

Yes, web workers cannot access the DOM directly, and they have a different scope, so you'll need to use message passing to communicate with the main thread.
