What is the difference between Node.js event loop and threading?

The Node.js event loop is a single-threaded model that handles asynchronous operations, while threading involves multiple threads for concurrent execution.

Can you explain how the event loop works in Node.js?

Sure! The event loop continuously checks the call stack and the message queue, executing tasks from the queue when the stack is empty.

What are the advantages of using the event loop over threading?

Using the event loop can lead to better performance and lower memory usage, especially for I/O-bound tasks, as it avoids the overhead of managing multiple threads.

Are there any scenarios where threading is preferred over the event loop?

Yes, for CPU-bound tasks that require heavy computation, threading can be more efficient as it allows parallel execution on multiple cores.
