Modern JavaScript from the Beginning - Second Edition - Callback to Promise Refactor

The video tutorial explains how to handle asynchronous code in JavaScript using callbacks and promises. Initially, it describes the use of callbacks to manage asynchronous tasks, such as creating and retrieving posts. The tutorial then refactors the code to use promises, highlighting the benefits of promises over callbacks. It also covers error handling with promises, demonstrating how to use the 'catch' method to manage errors effectively. The tutorial provides a practical example of converting callback-based code to promise-based code, ensuring a better understanding of asynchronous programming in JavaScript.

What is the purpose of using callbacks in the create post function?

Explain how promises improve the handling of asynchronous code compared to callbacks.

Describe the process of refactoring the create post function to use a promise.

How does the implementation of a callback function change the order of operations in the create post function?

What is the significance of the 'then' and 'catch' methods in promise handling?

What happens if an error occurs during the execution of the create post function?

How do you handle errors when using promises in JavaScript?
