Just curious..

So this is me just being curious, but the second method of creating a function in the anonymous.js file seems odd, I cant see how it would be any better than the way you taught in the random.js file

You're right, in these examples there's not really any significant difference. At this point they just want you to be able to recognize both kinds and understand them when you see them in other code.

But in more complex code, function expressions can be useful for situations involving callbacks, hoisting or closures. If you continue with your JavaScript studies, these concepts will be introduced in later courses. Or you can find more information on this MDN documentation page.
