Node.js: The Road to Workers

on YouTube ↗28m

" summary

Node 10 ships an experimental worker_threads module (enable with --experimental-worker) that embeds separate V8 instances in threads, supports message ports, transferring ArrayBuffers and SharedArrayBuffer + Atomics, and can eval inline code or run filenames. A user reports 50% speedup (5ms → 2ms) in one case. DevTools debugging works; native handle passing and Windows polish remain unfinished, and APIs are still allowed to change while experimental.
