Callbacks are an essential part of asynchronous programming in JavaScript. They allow you to execute code once a certain task has completed, making them ideal for handling time-consuming operations such as file I/O or API requests.

However, with great power comes great responsibility, and managing errors in callbacks can be challenging. In this article, we’ll explore some advanced techniques for error handling in JavaScript callbacks, so you can write cleaner, more reliable code.

Understanding Errors in JavaScript

Errors in JavaScript occur when something goes wrong during the execution of your code. This could be due to various reasons, such as trying to access a property on undefined or null, dividing by zero, or attempting to parse invalid JSON data. When an error occurs, it gets thrown and passed up the call stack until it is either caught or reaches the top-level scope, where it terminates the program.
