What is the solution to: Challange Task 2 of 2, in JavaScript Basics, Functions parameter/var echo...?

Task 1: function returnValue(arg1){return arg1;} ... this is ok. Task 2....I do not get it.

script.js 
function returnValue (arg1){
  return arg1;
}
index.html 
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

An example solution could be:

var echo = returnValue ('anyArg');

The parameter just needs to be passed in as a string as per the question.

You created the function already. Now you just call it, and assign the value it returns to a variable named echo.

Just add something like this (you can pick any string you like) after the definition you made in step 1:

var echo = returnValue("any string");
