mongoose00318 :
I am trying to get refreshed on jQuery so I bought O'Reillys jQuery cookbook. I'm having trouble with the exercise on using andSelf() to manipulate the parent of the selected element; though my code is exactly like the books.
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
</head>
<body>
<div>
<p>Paragraph</p>
<p>Paragraph</p>
</div>
<script
src="https://code.jquery.com/jquery-3.4.1.js"
integrity="sha256-WpOohJOqMqqyKL9FccASB9O0KwACQJpFTUBLTYOVvVU="
crossorigin="anonymous">
</script>
<script>
$('div').find('p').andSelf().css('border', '1px solid #993300');
</script>
</body>
</html>
From my understanding my jQuery should add a border to the div but it doesn't. When I remove andSelf() it does add a border to the 2 p tags though. Am I doing something wrong?

In the jQuery API Documentation:
This API has been removed in jQuery 3.0; use
.addBack()instead, which should work identically.
$(function() {
$('div').find('p').addBack().css('border', '1px solid #993300');
});<div>
<p>Paragraph</p>
<p>Paragraph</p>
</div>
