What are the communication patterns in web workers?
Web workers communicate with the main thread using a messaging system. They send messages via the postMessage() method.
Can you explain how the postMessage() method works?
Sure! The postMessage() method allows web workers to send data to the main thread, and vice versa, using structured cloning.
What types of data can be sent between the worker and the main thread?
You can send various data types, including strings, numbers, objects, and even ArrayBuffers, as long as they can be cloned.
Are there any limitations to using web workers?
Yes, web workers run in a separate global context, so they can't access the DOM directly and have limited access to certain APIs.
