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 best suited for web workers?
Web workers are ideal for tasks that require heavy computation, like image processing, data analysis, or any operation that might freeze the UI if run on the main thread.
Are there any limitations to using web workers?
Yes, web workers cannot access the DOM directly, and they have a limited set of APIs available. They also communicate with the main thread via message passing.
