Please note that in the script
tag,
you can either write code or include a file.
Trying to do both at the same time won't work.
So the following code doesn't work:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<script src="script.js">
alert('text');
</script>
</head>
<body>
</body>
</html>
