How does Facebook grab article text when pasting an url?

I'm a little curious about this useful feature of Facebook. When I paste the URL into "What do you have in mind?" box, it almost perfectly receives the body of the article. How does Facebook do it?

Thank!

This is part of how Facebook Share works.

The Linter URL is also very useful. For example, if we test it with this very question , you can scroll down and see where it gets data from

", Facebook . URL- " ?' , . Facebook ? " <description> <p>
