I don't understand this challenge. When is says the function takes a parameter, does it mean an argument?
How do I pass in an array?

You would pass an array into a function in JavaScript like you would any other parameter. Lets say you have a function that just returns what it is passed, like this:
function echo(parameter){
return parameter;
}
You can pass it anything you want, and it would simply return what you passed. This includes arrays. One way you can pass an array to it is like this:
var array = [1,2,3,4,5,6]; //You can make this array hold anything you want. I just put in some numbers
echo(array);
Or you can simply pass an array literal, like this:
echo([1,2,3,4,5,6]); //Again, you can make the array hold anything you want

16,945 PointsThanks, that's very helpful. I have completed the challenge now.
I still don't get the question that's set for the challenge though. At no point in my correct solution did I use an array, at least intentionally, but the question made me think I had to.
