How Node.js Processes Asynchronous Requests with Its Event Loop
When Node.js receives an asynchronous request, it packages the request into an object, delegates processing to a worker thread, enqueues the completed object, and then its event loop repeatedly pulls objects from the queue to invoke their callbacks, enabling non‑blocking I/O.
Node.js receives an asynchronous request, packages it into a request object, and hands it off to a worker thread for processing.
After processing, the request object is placed into the event queue.
Node.js runs an event loop that, on each iteration, retrieves request objects from the queue and executes their callback functions.
