I have no idea of the true syntax. 20th try and nothing.

fuction (sayHi)() alert('Hi') } ()function say HI (Hi) alert sayHi(); }

script.js 
function sayHi()
alert("Hi") }
(Hi)function sayHi(Hi) 
alert 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>

The sayHi function should have a { to start the code block.

function sayHi() {
  alert("Hi") 
}

To call the function, add the line sayHi() outside of the function.
