Can anyone clarify this for me?

That's just how we declare a function in javascript. When you'll built more complex ones, you'll place the arguments inside the parentheses.
function addTwoNumbers(a, b) {
let result = a + b;
return result;
}
When you'll call the function you'll write
addTwoNumbers(3,4)
and it will return you 7 ;-)
In this case, there are no arguments in the function so we type nothing in it!
That's just that simple.

2,009 PointsNice response Theo. I just also want to say to the OP that this course is really just an introductory course to some of the aspects of Web Development. This is a great start for any newbie as it covers some networking, web-based development & whatever else is yet to come.
That being said, when you cover a Javascript module on Treehouse that is 6-8 hours long you'll definitely learn of passing parameters (As Theo has demonstrated above), functions & a whole lot more in great detail.
