Match the asynchronous programming concept in Node.js with its corresponding description:

Callbacks

Promise chaining

We can use the await keyword only inside an async function in JavaScript

What is meant by the term "callback hell" in the context of asynchronous programming?

A situation where callbacks are used excessively, leading to slower program execution.

A condition where callbacks are prone to causing memory leaks in Node.js.

A limitation that prevents the use of callbacks in certain asynchronous operations.

A scenario where callbacks are nested deeply, resulting in difficult-to-read and maintain code.

What is the purpose of asynchronous programming in Node.js?

To eliminate the need for callbacks

To handle long-running tasks without blocking the execution of other tasks

To make the code execution faster

To simplify the code structure

Which of the following is an advantage of using Promises over traditional callback-based asynchronous code in Node.js?

Promises can only be used with certain built-in Node.js functions

Promises eliminate the need for error handling in asynchronous operations

Promises offer better performance and faster execution

Promises provide a more structured and readable way to handle asynchronous operations

What are the possible states of a Promise in JavaScript?

Fulfilled
