I was reviewing learned materials about function

Hello there,

Here is a script

   function message (parameter) {
      document.write('Document message');
    }
    console.log(message ('passing argument'));

Why when I run this function document writes its message to the website but console doesn't.

Hey Durdona,

The problem lies within your function. When you're passing in information to a function via a placeholder variable, you should use that variable to determine the output. So, you should change the string 'Document message' inside the function to the variable parameter that way document.write() will receive the value passed into it in the form of the placeholder parameter.

 function message (parameter) {
      document.write(parameter);
    }
    console.log(message('passing argument'));

As I see all functions use parameter names within the function

function getRandomNumber(lower, upper){
var random = Math.floor(Math.random() * (upper - lower + 1)) + lower; 
return random;

console.log(getRandomNumber (1, 6));

Thank you ! Didn't pay attention to time sorry

Absolutely right! Nothing to be sorry about :) We all make mistakes, and so long as we learn from them, we keep on being awesome! haha :P

My pleasure!
