Answer 1

in the header, loader.js is connected,
which never changes (or rarely enough),
this file loads the necessary js files that change often.
and also in the loader, implement the logic for resolving situations with caching, with versioning, and so on.

Answer 2

When writing the script address in the src attribute of the script tag, add a request like ?v1.0
I.e.

<script type="text/javascript" src="/js/core.js?v1.0"></script>

And after update change to

<script type="text/javascript" src="/js/core.js?v2.0"></script>

(or some other way)

Answer 3

TS should not forget that different tama Chrome and other IE with factory settings may be paranoid not to update the files.
Therefore, a good option is to only include mtime files (or version or whatever) in the file name, or change it completely.
Or completely and completely demolish file caching.
There are no other STABLE options.
