Open link in new window or focus to it if already open

Question

I have a link which should open in a new tab, but if the tab is already open, just switch to it. I\'ve tried with javascript, wnd = window.open() and than wnd.focus(), that

Answer 1

In Firefox 66 and Chrome 74 this works for me:

 wnd = window.wnd && window.wnd.close() || window.open(url, "wnd");

Not tested in other browsers. Thanks to roberto (in the comment of the MarkZ answer) to point me on this solution. (I could not add a comment in that answer due my lack of reputation, sorry).

window.focus() solution was not fit my needs as this other one.
