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.
