Как правильно завершить работу объекта web worker?

To properly terminate a Web Worker object in JavaScript, you need to call the terminate() method on the worker instance. This immediately stops the worker's execution and releases resources.

Example:

const worker = new Worker('worker.js');

// After the work with the worker is completed
worker.terminate();

It is important not just to stop listening to messages, but specifically to call terminate() to avoid memory leaks and unnecessary load on the browser. You can also send a message to the worker requesting it to finish, if you need to perform some cleanup inside the worker, and then call terminate() from the main thread.
