Create a function named sayHi. Don't put any code inside the function yet, just create the basic structure with an empty

function sayHi () {

This is what I put and I keep getting an error. What is the problem? Thank You.

script.js 
function sayHi () {
index.html 
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  <title>JavaScript Basics</title>
</head>
<body>
<script src="script.js"></script>
</body>
</html>

You need to add a closing bracket 

      function sayHi () {}
            ```

If JavaScript sees function declaration without PAIR of bracket it will throw a syntax error.
