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

  return arg1;

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");
