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 are some common use cases for the event loop?

Common use cases include handling user interactions, making network requests, and managing timers.

Can you give an example of how it works in practice?

Certainly! For example, when you set a timer with setTimeout, the callback function is added to the queue and executed after the specified delay, even if other code is still running.
