Answer
The event loop manages asynchronous operations and ensures Node remains responsive without blocking.
Quick Answer
The event loop is the core of Node.js — it's what allows JavaScript to handle multiple operations without blocking. It continuously checks if there are pending callbacks to run (timers, I/O, network). When an async operation completes, the event loop picks up the callback and runs it. This is how Node handles many connections with one thread.
