What is the event loop in JavaScript?
An example of an AI chatbot conversation about the event loop in JavaScript.
Can you explain what the event loop is in JavaScript?
Sure! The event loop is a mechanism that allows JavaScript to perform non-blocking operations by using a single thread.
How does it handle asynchronous tasks?
It uses a call stack and a message queue. When an asynchronous task completes, its callback is added to the queue.
What happens if the call stack is busy?
If the call stack is busy, the event loop will wait until it's empty before executing the callbacks in the queue.
Can you give me an example of how it works?
Certainly! For example, if you set a timeout, the event loop will wait for the timeout to complete and then execute the callback.
