How Node.js Handles Async Operations
Node.js is designed to be asynchronous and non-blocking, making it highly efficient for handling multiple operations at once. Unlike traditional multi-threaded architectures, Node.js operates on a single-threaded event loop, meaning it executes JavaScript code in a single thread but can still handle multiple tasks concurrently. This is achieved through asynchronous I/O and event-driven programming, allowing Node.js to remain lightweight and performant even under heavy workloads.
