A Crash Course on Worker Threads
summary
Node.js adds worker_threads (introduced in 10.5, stable in 12.11, use 12.15.0 for security fixes) and demonstrates concrete code: a one-file hello world, passing workerData, using parentPort.postMessage, and terminating with terminate() that returns a promise. The talk shows sharing/transferring ArrayBuffers and pooling, and measures performance: single-thread BFS ~14s, bi-directional ~3s, and two parallel workers under 700ms, with links to slides and repo.
