for example, the last time I packaged a project, the name js was abc.js. Then I packed it this time, put the packaged files on the server, and then opened the unupdated website in my browser before I put it on the server. Well, after I updated this version, because the last js file has been deleted, the page opened by my browser can no longer be clicked, because the js files are gone, so it has to be refreshed before the browser reloads my new js file. How to solve this problem. It is possible to load new js files without refreshing them.
