Hi Diyan,

  • The only statement you want inside of this function is a return statement, which will simply return the argument that you are passing in. This is practice for getting accustomed to writing functions and return statements.
  • The variable initialization will happen outside of your function. The reason for this is that we want to call the function from outside, and store whatever results we get inside of a variable that does not belong to the function itself. Since the function takes one argument, we'll pass in one. The challenge asks us to make this argument a literal string value.
function returnValue(hello) {
  return hello;

var echo = returnValue('example argument');

Hope this helps.
