What is the callback queue in JavaScript?

The callback queue is a mechanism that holds messages or tasks waiting to be executed after the current execution context.

How does it work with the event loop?

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

Can you give me an example of how it works?

Sure! When you use setTimeout, the callback function is placed in the callback queue after the specified delay.

What happens if there are multiple callbacks?

They are executed in the order they were added to the queue, ensuring a first-in, first-out (FIFO) processing.
