Creating a fuction

it's asking for the code needed inside the function that would make a dialogue appear. I've tried a few ways but idk.

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 have created right an empty function as the 1st task of the challenge require. Then you have to write the code you want (inside the function code block) to be executed when you invoke the function. 

function sayHello() {
     //my code here
     console.log('Hello there!');
}  
//Here we only define the function and it is not being executed. So you will not see any result.

After you have define the function to see the result of your code you have to invoke the function- Function Invocation. To invoke a function you write the name of the function you have created and parenthesis:

sayHello();
//sayHello() will be executed and will appear in the console.
