jQuery has method

If we need to filter a set by elements that have certain descendants, we can use the has method:

For example, let's say we have the following HTML code:

html<p>text</p>
<p>text</p>
<p><b>bold</b> text</p>
<p><b>bold</b> text</p>

Let's select only those paragraphs that have the tag b inside and put the text '???' at the end of them:

javascript$('p').has('b').append('???');
