Parallel Universes: Node.js
summary
Shows how Node.js achieves parallelism by spawning worker threads (and forking processes) and wiring explicit message passing between child and parent; walks through a concrete forker/worker example that actually sends messages back and forth. Demonstrates a failing variant that uses shared memory race conditions and explains the subtle bug that appears. Includes live code behavior so the built example either succeeds with message serialization or breaks when memory is shared.
