Now, leaving the code from the last task in place, add 3 names to the beginning of the list using the unshift( ) array method. The final array should have 9 names in it. Do not attempt to display the names - only add them to the array.

I try'd everything

script.js 
var guestList = ['Sandra', 'Omar', 'Magnus', 'Becky'];
guestList.push('Mars', 'Mary');
index.html 
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">

<body>
<script src="script.js"></script>

</html>

You have to leave the code you added from task one, so you should end up with:

var guestList = ['Sandra', 'Omar', 'Magnus', 'Becky'];
guestList.push('Mars', 'Mary');
guestList.unshift('Alex', 'Jason', 'David');

You have done a good job! Two mistakes, though. :)

This first mistake is you only have added two elements to the array, while the challenge expected exactly three. Try adding one more element :smile:

The most important error is that the challenge wanted you to put the names at the beginning of the array, and the .push() function puts the names at the end of the array.

Good luck!

It does work. Maybe you need the code:

var guestList = ['Sandra', 'Omar', 'Magnus', 'Becky'];
guestList.push('Mars', 'Mary', 'Moran');

Try:

var guestList = ['Sandra', 'Omar', 'Magnus', 'Becky'];
guestList.unshift('Mars');
guestList.unshift('Mary');
guestList.unshift('Moran');

Good luck!
