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

Posted by Weston Hagan

Why does adding my variable 'echo' cause Challenge Task 1 to fail?

I'm working through the challenge tasks and task one- create a function called returnValue - was passed with the code:

function returnValue(value){

return value;
}

but when I move to task 2 and add :

returnValue("My Argument");
var echo = value;

The code checker claims that task 1 is no longer working. Simply commenting out my last 2 lines and rechecking the work makes Task 1 pass again.

Can anyone help explain how I'm breaking the function by calling it and storing the value in a variable? Thanks!

Hi Weston,

I edited your code to make it more legible, click on edit post to see how i did it.

Value just exists inside the function scope. To get that value you need to assign a variable to the result of that function, like so:

var echo = returnValue("My Argument");
