Node.js: The Road to Workers
summary
Node.js ships experimental threading in Node.js 10 and 11 behind the --experimental-worker flag, implemented as a new worker_threads module that spawns independent Node instances with shared memory (SharedArrayBuffer + Atomics). Anecdotal benchmarks claim a 50% speed up on CPU work versus single-threaded code; startup costs remain nontrivial and native add-ons often need fixes. The feature exists, runs, and is usable for CPU-bound tasks, but remains experimental and evolving.
