JavaScript Asynchronous Programming with JavaScript Asynchronous JavaScript with Callbacks Implement a Callback

Instead of using annonymous functions, couldn't we have created named functions instead?

Wouldn't this look a lot cleaner and easier to follow. Why does Guil keep contnually creating anonymous functions instead of making the extra effort to create a named one?

Named functions would indeed work also. But since the callbacks are generally not used anywhere else, it's a common practice to define them as anonymous function expressions right in the call where they are used.

So you can set up your callbacks differently if you want, but if you work with other people's code it will most likely look very much like the examples you see in the videos.
