What are the differences between promises and callbacks in Vue.js?

In Vue.js, callbacks are functions passed as arguments to other functions, executed after a task completes. Promises, on the other hand, are objects that represent the eventual completion (or failure) of an asynchronous operation, allowing for cleaner and more manageable code.

Can you give me an example of using a callback in Vue.js?

Sure! Here's a simple example: you can use a callback in a method that fetches data. After the data is fetched, you can call a callback function to process that data.

What about using promises? How does that look?

Using promises, you would typically return a promise from your data-fetching method. You can then use .then() to handle the response and .catch() for errors, making the code more readable.

Which one is better to use in Vue.js?

Promises are generally preferred for handling asynchronous operations in Vue.js due to their cleaner syntax and better error handling.
