I won't dare to predict where industry "is going to move", since I'm not really a frontend developer, so what do I know anyway (and especially since it seems to switch directions every couple of years, and mostly being pulled in all directions simultaneously). But personally I still prefer to use stand-alone JS-scripts and libs included directly into the page, if I can. Mostly because I hate having to deal with complicated (and, importantly, rather slow) build process just for the sake of a couple of web-pages, when the real stuff is some totally invisible backend processing or maybe some sort of HTTP API to be used by other services.

Also, honestly, I really just don't know what's the "correct" way to do things in 2024 on frontend, and I don't know where to even look for a guide, if I don't really want to spend next 6 months entirely in the pursuit of attaining "real" frontend-dev proficiency, but ultimately just to make working stuff, even if it doesn't quite follow the v2024 web-etiquette.
