Where to put the js file on the page so that it works for the changed link?

Question

JavaScript

Using the history api, the history.pushState({}, "", href) method I change the link,
I load the content via ajax, and, as it were, a new page,
the js file is on the main page,
if you refresh the page, then js does not work, as I understand from the fact that the link is now different,
what then to do? js file needs to understand that an update is taking place, and not follow the link
