Node.js

What is the Node.js event loop and why does it matter for performance?

The question is about Node.js .

Answer:
The Node.js event loop is a single-threaded process that manages I/O operations asynchronously without blocking execution. When a Node.js server receives an HTTP request, it delegates I/O tasks to the system kernel and keeps accepting new requests. This design allows Node.js to handle thousands of simultaneous connections on just one thread, making it highly effective for API services with large request volumes and low CPU-intensive workloads.
