Which of these best describes Node.js's concurrency model?

  1. A Multi-threaded with one thread per request
  2. B Single-threaded event loop with non-blocking I/O delegated to the system
  3. C Process per request
  4. D Synchronous request handling
Answer

Single-threaded event loop with non-blocking I/O delegated to the system

One thread runs JavaScript while libuv handles I/O asynchronously. This scales well for I/O-bound work and poorly for CPU-bound work.
