How does Node.js handle asynchronous operations?

Node.js uses non-blocking I/O, the Event Loop, libuv, and callback queues to execute asynchronous operations efficiently.

Cross-check this information using these trusted sources:

libuv manages the Event Loop, thread pool, asynchronous I/O operations, and many low-level runtime features.

No. Node.js delegates the operation and continues executing other code while waiting for completion.

Certain operations such as file system access and cryptography use libuv's thread pool.
