How does Node.js handle asynchronous operations to ensure non-blocking behavior?

Node.js utilizes an event-driven, non-blocking I/O model to manage asynchronous operations efficiently. Instead of waiting for an operation to finish, Node.js continues executing the remaining code. Once the asynchronous task completes, a callback function is triggered to handle the result. This mechanism allows Node.js to process multiple requests concurrently, significantly improving scalability and performance.

This non-blocking behavior is especially beneficial when building high-performance web applications that require real-time capabilities. It also plays a key role in custom web development where efficient handling of I/O operations is critical for optimal user experience.
