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

This seems like it should work, but I can't figure out what's wrong.

function returnValue(argument) {

return argument;

}

var echo = returnValue;

returnValue("hellooooooo");

script.js
function returnValue(argument) {

  return argument;

}

var echo = returnValue;

returnValue("hellooooooo");

You are close. You need to pass an argument to the function like this:

var echo = returnValue("hellooooooo");
