function returnValue(str) { var echo = return str; } How to pass and store the results in a var echo?

function returnValue(str) { var echo = return str; }

How to pass and Store the results of the function in a variable named echo.

Now that you've created the returnValue function, call it, by passing it a literal string value -- a series of characters in quote marks like this: 'My argument'. Store the results of the function in a variable named echo.

script.js 
function returnValue(str) {
  var echo = 
  return str;
}
index.html

In anthoer word, create a var echo outside the function and pass the function name to it. Something like this. Your code is almost right except that the echo var needs to be outside the function and pass the returnValue() to it.

function returnValue(one) {
    return one;
}
var echo = returnValue("My argument");

Ok so all your function is going to be doing is returning something. Outside of your function you need to assign the "call" (returnValue()) to the variable echo. Make sense?

Here is my solution:

function returnValue(food){
  return food;
}
var echo = returnValue("beef");
