I am learning about the merits of including rel="noopener noreferrer" for external links.
What is the difference between these two attribute values? When should I use noopener, and when should I use noreferrer?

rel=noreferrer is used so that when a user clicks on a hyperlink and is transferred to a new location, no referrer information will be leaked to the destination link. Meaning, it will not be possible for the destination to know where that user came from.
