What is the JavaScript event loop?

Can you explain what the JavaScript event loop is?

Sure! The JavaScript event loop is a mechanism that allows JavaScript to perform non-blocking operations by using a single thread.

How does it handle asynchronous code?

It uses a call stack and a message queue. When asynchronous code is executed, it gets pushed to the queue, and the event loop processes it when the call stack is empty.

What happens if there are multiple tasks in the queue?

The event loop processes tasks in the queue one at a time, ensuring that each task is completed before moving on to the next.

Can you give an example of how it works?

Certainly! For instance, if you set a timeout with setTimeout, it will be added to the queue and executed after the specified delay, even if other code is still running.
