Referring to 2nd link above, we're using jquery (though may not be magento).

As instructed above, to run in Chrome console (Alt-Shift-I  or  F12 to invoke console) & enter:
  jQuery.get('https://sakurity.com/jqueryxss');

Q1:
So to verify my URL, I replace sakurity.com  with my URL or I load in the Chrome'
browser my URL & in the console, I enter the above jQuery.get ...  ?  
How do I use it to verify my URL?

Q2:
Tried several URLs & got various returns below, are they pop-ups or what's the
expected value (in the pop-ups) that will indicate my URL is vulnerable or what
other values mean?   The values returned that I got so far:

a)
jQuery.get('https://www.myURL.com/jqueryxss');
{readyState: 1, getResponseHeader: ƒ, getAllResponseHeaders: ƒ, setRequestHeader: ƒ, overrideMimeType: ƒ, …}

b)
jQuery.get('https://sakurity.com/jqueryxss');
{readyState: 1, getResponseHeader: ƒ, getAllResponseHeaders: ƒ, setRequestHeader: ƒ, overrideMimeType: ƒ, …}

c)
jQuery.get('https://www.google.com');
{readyState: 1, getResponseHeader: ƒ, getAllResponseHeaders: ƒ, setRequestHeader: ƒ, overrideMimeType: ƒ, …}
