You can access the end part of your url by using window.location.pathname.
For the website site.com/page16 - window.location.pathname returns the string "/page16".

Next you could have a function that checks to see what the current pathname is and terminates early if the pathname doesn't match /page16.

For example:

const subPageFn = () => {
  // terminates early if subpage doesn't match page16
  if (window.location.pathname !== '/page16') {
    return
  }

  // runs page16 specific code here...
}

Then you'd call the function in any page by using

subPageFn()
