1,546 Points1:25: "function as a parameter" OR "function as an argument"?
"you can clearly see function as a parameter..."
Isn't the function an Argument instead or a parameter..? If I'm mistaken please correct and help me get the hang of this :)

1,546 PointsYep. The way I've understood them is:
const exampleFunction = (thisIsAParameter) => console.log(thisIsAParameter);
exampleFunction("thisIsAnArgument");
...but would hope for a comment from teamtreehouse whether I've misunderstood :)

But it's easy to get those terms reversed and it appears that's what the instructor did here. Good catch!

231,248 PointsYou're understanding is completely correct based on my own JavaScript experience. But I understand if you want official confirmation of the error in the video.
I'd suggest tagging the teacher, but I understand Andrew is no longer with Treehouse. But you might want to report this as a video bug directly to the staff via the Support page. Their response would probably confirm the error in the video. And if you're the first to report it, it could get you the "Exterminator" badge.

14,940 PointsThis isn't the first time I've heard an instructor use "parameter and arguments" interchangeably. According to MDN parameters are arguments:

231,248 PointsThe MDN usage seems correct to me. A parameter is a name used as a placeholder for an argument which will be passed to the function at a later time.

14,940 PointsIt's hard to figure because like I mentioned I've seen high profile instructors use them interchangeably like this. It's possible they come from a variety of programming backgrounds before they settled on JavaScript. Wikipedia goes into a bit more depth on the subject:
