JavaScript JavaScript Basics (Retired) Creating Reusable Code with Functions Passing an Argument to a Function

Do we make up our own parameter? I don't understand this question.

I'm sorry I don't even know what to ask, I'm just lost on this question I don't know what they're looking for. Do we make up parameters? Like do we make up a whole function like in the previous video?

For task one, you're not really making up parameters, the challenge wants you to create a simple function (name returnValue) with one argument and just return the argument.

You will use var to create the function.

var returnValue = function(arg) {
  return arg;
}

I hope this makes sense. If not, I recommend going back over some of the videos before moving on, as functions are a very large part of JavaScript programming.

Keep Coding! :)

Ah, thank you, I just didn't understand what they are looking for. Yes I think I'll go through the functions section again. Thank you!!

On the side note. Parameter and argument is used as the same thing, but they are a bit different. Parameter is used when you are building the function. It is a placeholder for a potential value. Argument is the actual value you will use later when the function is called. It helps me to remember the difference.
