Q: What are the performance trade-offs of using Web Workers? When can they actually hurt performance (e.g., small tasks, frequent postMessage calls)?

Use workers for CPU-intensive tasks (e.g., image processing, parsing) that take >10ms. Avoid workers for trivial tasks or when data transfer costs exceed processing gains. Minimize `postMessage` frequency; batch data when possible.

What are the performance trade-offs of using Web Workers? When can they actually hurt performance (e.g., small tasks, frequent postMessage calls)?

Workers add overhead for thread creation, message serialization, and data transfer. For small tasks, the overhead may exceed benefits. Frequent `postMessage` with large data can flood the event loop.
