When we refresh the page (F5, or icon in browser), it will first trigger ONUNLOAD event. When we close the browser (X on right top icon),It will trigger ONUNLOAD event. Now

Answer 1

I just tried this and it solved the issue: Create a sessionStorage object which will get destroyed when the user closes the browser. We can check the sessionStorage object to find if the user has closed the browser or refreshed the page(sessionStorage object will not be destroyed on page refresh).
