The windowExcludes is the inverse of windowIncludes. It is a case-sensitive function that is used to check if the current base url does not match the list of supplied urls. Since index pages can either be empty (i.e "") or "index", a frontslash ("/") can be used to denote an index page.

  if( windowExcludes('some/url') ){

     // url is not "some/url"

  }
                  

  
  $validUrls = ['some/url1', 'some/url2']; 

  if( windowExcludes($validUrl) ){

     // current url is not in accepted url's list

  }
