In Node.js, can you explain in detail how the event loop works and how asynchronous operations are handled by using the event queue and call stack? Provide practical examples to illustrate your explanation. |

The event loop in Node.js enables non-blocking execution by delegating asynchronous operations to the operating system and managing them through an event queue. As long as the call stack is empty, Node.js processes events from the queue. For example, when reading a file, the operation is placed in the queue and executed upon completion, avoiding blocking on the main thread of execution. |
