Node.jsQuestion 04 of 26
Why is Node fast?
Answer out loud or in your head first, then compare.
Answer
Mainly thanks to:
- V8,
- an event-driven architecture,
- non-blocking I/O,
- low overhead for many concurrent I/O operations.
Node is especially strong at I/O-bound workloads.
Heavy CPU calculations can block the main event loop.
How did it go? Be honest — “Not yet” puts the question on your review list.
