Q: How do you terminate a Web Worker? What's the difference between worker.terminate() and self.close()?

`worker.terminate()` is externally initiated; `self.close()` is self-initiated. No cleanup hooks; any ongoing operations are aborted. To gracefully stop, use a message to request shutdown and allow cleanup in worker.

Difficulty: 5/10

Web Worker lifecycle, Termination APIs, Main‑worker communication

`worker.terminate()` from the main thread kills the worker immediately; `self.close()` from inside the worker terminates itself. Both stop the worker instantly without waiting for pending operations.
