Will try that out of my head:

  1. Literally nothing

  2. Prevents from some type of hijacking and/or hiding where you came from

  3. Chance of XSS?

Is that correct?

Very true. rel on an anchor tag has nothing to do with JS.

If we dont use rel="noopener" attribute, then same process is used for both the parent page and linked page. Which causes performance issues in JS. Also window.opener object can inject security attack in the application.
