An example of an AI chatbot conversation about error handling in callbacks.
How can I handle errors in callbacks effectively?
You can handle errors in callbacks by using try-catch blocks or by passing an error-first callback pattern.
What is the error-first callback pattern?
The error-first callback pattern involves the first argument of the callback being an error object, followed by the result.
Can you give me an example of this pattern?
Sure! Here's a simple example: function fetchData(callback) { ... callback(err, data); }.
What if I want to handle multiple asynchronous operations?
You can use Promise.all or async/await to handle multiple asynchronous operations more cleanly.
