I have my "good.html" and "jquery.js" file in a folder on desktop called "jquery2."
Here is my code
<!doctype html>
<head>
<meta charset="utf-8">
<script type="text/javascript" src="jquery.js"></script>
</head>
<body>
<script type="text/javascript">
$(document).ready(function(){
console.log('ready');
});
</script>
</body>
</html>
