## TL;DR
Web Workers run JavaScript off the main thread and communicate by messages. They help with responsiveness but add lifecycle and data-transfer design concerns.

## Core Explanation
Workers are useful for CPU-heavy tasks, parsing, data processing, and other work that should not block user interaction on the main thread.

## Detailed Analysis
The repaired article cites MDN and the HTML Standard for worker behavior and the Worker interface.
