Hi there! The key to this is in the first word of your question. After our newly created function...

Here this function doesn't do very much. It accepts a value that we pass to it and then returns it. When it is returned it is immediately assigned to a variable named echo. I modified this so you can see what it looks like if we pass in the value "Jordan".

function returnValue(myValue) {
  return myValue;
}

var echo = returnValue("Jordan");

Our echo will now have the value "Jordan" assigned to it as that is what was returned by our returnValue function. Hope this clarifies things! :smiley:

Try this:

function returnValue(ferociousAnimal) {
  return ferociousAnimal;
}

var echo = returnValue('Red Fox');
