Why is it not working this way?

function alertRandom(){
  var randomNumber = Math.floor( Math.random() * 6 ) + 1; 
  return randomNumber;
};
alertRandom();
alertRandom();
alertRandom();
alertRandom();
alertRandom();



/* Is it necessary to add "alert(randomNumber)" command 
on line 3 and if yes what does this command convey?  */

function alertRandom(){
 var randomNumber = Math.floor( Math.random() * 6 ) + 1;
 return randomNumber; }; 
// here you call the function,
// but it's not yest displaying to the page
alertRandom(); 
//not sure how you are actually displaying it to the page
//if you want it to alert to the page you would do this
alert(alertRandom());

function alertRandom(){
  //You have stored your random number in the variable "randomNumber"
  var randomNumber = Math.floor( Math.random() * 6 ) + 1; 

  /*
  * Using "return" will display the random number in your browsers javascript console 
  * but not on the webpage or in a pop-up box as we have done in previous excercises
  */
  return randomNumber;

  /* 
  * Use the alert() function to display the random number in a popup. Now when you 
  * call your alertRandom() function it will in turn call the alert() function to display 
  * your number.
  */
  alert(randomNumber);
};
alertRandom();
alertRandom();
alertRandom();
alertRandom();
alertRandom();

because you just put return inside the function, to use the function with return just call it like this ::

<script>
alert(alertRandom);
</script>

Hi, Atul R the error is because the semicolon at the end of the closing curly braces. use it, just when you're using the other way to create a function called: function expression

I hope this helps clear it up. :)
