re: Using noopener has another advantage. If the new website takes a lot of resources, your site may be slower - this does not happen if you use noopen...
 

Yes missed them!

Whenever the opener object is defined in the new website, both run with same event loop. (i.e) there is only one process handling both tabs.

May be the approach of creating anchor tag dynamically through js and clicking it is the best approach that considers all cases ,if we want to open the new tab through JavaScript
