What is the difference between event loops and callbacks in JavaScript?

Event loops manage asynchronous operations, while callbacks are functions executed after an event occurs.

Can you explain how the event loop works in a bit more detail?

Sure! The event loop continuously checks the call stack and the message queue, executing tasks as they come.

How do callbacks fit into this process?

Callbacks are pushed to the message queue when an asynchronous operation completes, waiting for the event loop to execute them.

Are there any downsides to using callbacks?

Yes, using too many callbacks can lead to 'callback hell', making code harder to read and maintain.
