If Node.js is single-threaded, how does it handle many requests?
Node.js delegates asynchronous operations to the operating system and libuv while the Event Loop coordinates completed tasks, allowing many concurrent requests to be handled efficiently.

More FAQs in Why Is Node.js Single-Threaded?
Node.js uses a single-threaded JavaScript execution model to simplify programming and efficiently handle I/O-heavy workloads using non-blocking operations.
JavaScript execution is single-threaded, but Node.js uses additional threads internally through libuv's thread pool for tasks such as file operations, DNS lookups, and cryptographic functions.
The Event Loop monitors asynchronous operations and moves completed callbacks to the Call Stack when JavaScript is ready to execute them.
