I'm not entirely sure what am doing? How are you supposed to set the value of ECHO to be the results returnValue and a

really confused?

script.js
var returnValue = function(blacks) {
  var cookies = blacks 
  return cookies;


}?

You have the right code now but in the wrong place

Remember what I said earlier: The new code will come after the function (you seem to have it inside the function here). Also, you seem to have added another definition of "returnValue", but you should only have one.

Don't get confused by Tommy's suggestion, just put your function back to the way you had it when you originally passed task 1. Then put that new line of code after the closing brace of the function.

Your function should not end with a question mark.

But otherwise it looks good, and should pass task 1. Then for task 2, after the function, you create a new variable named "echo" and initialize it by calling the function.

You know how to create an initialize a variable because you did it in your function. The only difference this time is calling the function for the value to assign it.

No it's not task one I was referring to I meant task two.
//this is were im confused at not sure how to pass it it don't make sense to me for some reason. var returnValue = function(blacks) { var cookies = blacks return cookies; var echo = 'Hi'; return echo + 'Hi';

} document.write( returnValue(3,'Hi') );

For task 2, don't make any changes to the function itself.

Leave your function just as it was in task 1. The new code will come after the function. You will create a new variable named "echo" and initialize it by calling the function. Here's a few more hints:

  • you will not use any other functions (such as document.write)
  • you will only initialize the new variable
  • all of task 2 can be done with a single line of code

You're right, and this is certainly more compact. But the other version does satisfy the challenge and this doesn't address the question.

i'm running out of options to what to do?

var returnValue = function(blacks) { var cookies = blacks return cookies; function returnValue(abc) { return abc; } var echo = returnValue('alphabet');

}
