    why? it does not like anyone would see it, or are you talking about server-side js? Commented Jul 4, 2020 at 7:16

    there is a method document.createComment(); but may i know the purpose of injecting comments after the closing tag? Commented Jul 4, 2020 at 7:20

    Shouldn't you do that on the backend (if at all) instead of in the browser? Commented Jul 4, 2020 at 7:29

    You are mistaken if you think that using javascript within the page will modify the file itself stored on server. Why can't you just do it manually? Commented Jul 4, 2020 at 7:31

    Only for the life of the page in browser. Each time you load the page it pulls the original file from the server. There is nothing you can do with javascript in the page to actually modify the file on the server. That would require being done by server side programming language Commented Jul 4, 2020 at 7:36

Wow! Amazing never crossed my mind
Nice! it works!
Is there a way to put line break with this? like </html> Break break <!-- Like this --> Break break
@Asad: For adding any break, we need insert <br> tag, which can't be added after </html> ending tag. If user tries to do so, it thows console / functional error. Thanks!
@solanki is it possible to replace </html> itself with 2 linebreaks ? like done with div inner html
