Answer 5

To handle urls and show a 404 for exmple, you need a javascript URL router. There are many frameworks and libraries which you can use. Like: react, angular, vue, etc. Or you can install url-router using npm: url-router -npm.
If you don't want to use any of those, then you can create your own url router.
or you can build something simple like this:
const pages =["india","germany","belgium","albania",....];
then use:
const page = pages.find(c=> window.location.protocol +"/"+window.location.host+window.location.pathname.lastIndexOf(c)>-1);
if(page == undefined){
//REDIRECT TO PAGE NOT FOUND
}
I would still advice to use a router framework or library for js.

Location.Search is used to search a part of the url.
IndexOf can be used as well to look for 1 to many chars in a string.
