Hi Noel,

It's good attempt here but you need to include a closing script tag and make sure that is inside your body tags.

You also need to include the JavaScript alert() method and pass in the relevant string there inside your parentheses.

Good luck.

Your code should look like this

<!DOCTYPE HTML>
<html>
    <head>
     <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
     <title>JavaScript Basics</title>
    </head>
    <body>
      <script>
        document.write("warning!");
      </script>
   </body> 
</html>

There are 3 ways to write javaScript :

1- inline

   <button type="button" onclick="myFunction()">Try it</button>

2- internal ( you should add script tag inside the body )

   <body>
     <script>
       your code goes here
    </script>
   </body>

3- External ( you should link your file inside the head )

   <head>
      <script src="myScript.js"></script>
   </head>

Is it not supposed to be

alert("Warning!");

instead of document.write?
