What is callback in Nodejs? Callback isan asynchronous equivalent for a function. A callback function is called at the completion of a given task. Node makes heavy use of callbacks. This makes Node.js highly scalable, as it can process a high number of requests without waiting for any function to return results.
What is callback queue? Queue Callbacks. A queue callback is a flow option presented to a caller waiting in a queue. After waiting a specified length of time, the caller can choose to receive a callback from an agent when their request reaches the top of the queue instead of waiting on the phone.
How does event loop work? The Event Loop has one simple job — to monitor the Call Stack and the Callback Queue. If the Call Stack is empty, it will take the first event from the queue and will push it to the Call Stack, which effectively runs it. Such an iteration is called a tick in the Event Loop. Each event is just a function callback.
