Why would the project have hundreds of JS files? Usually I might have something like main.js which handles universal page elements like the search bar in a site-wide navbar, then, if necessary, a few this-specific-page.js files which handles elements which are specific to this page or site section. If any libraries are needed, try first to just link them in using CDNJS or the like, so no need to store them locally or bundle them in our own scripts - I know there are downsides to relying on external CDNs for such things but in practice it just works. Easy peasy.

But first, I try to avoid using JavaScript in the first place when not strictly necessary. This means server-side rendering as much as possible rather than doing the glacial "load an almost entirely blank page, load giant JS blobs, then load the page content via AJAX and hope that nothing goes wrong in that process, sorry slow connection users, non-standard browser users, and search engine bots" approach which thankfully is finally starting to see some pushback.

Here's what the person you're responding to said:

And you replied:

Please connect the dots for me.
