RefluxJS vs jQuery

I use jQuery at the moment because I use it for a lot of years already, but now Bootstrap 5 decided to switch to JavaScript, I am thinking of switching to an alternative.

I use jQuery only for the DOM integration, animations and ajax calls because JavaScript calls to a class looks such a long call. I like the way of jQuery with $(document).on('click','.something',function() {});

By the way, I like to keep using HTML, PHP and Bootstrap as I do now.

I have made an extended effort to drop frameworks completely if they are not actually needed. While I still use JS Frameworks like Vue, Angular and React ( if I have too ), I see far too often devs / teams deciding to build a single page site entirely in a framework, rather than just using HTML, CSS and a little JS.

I personally feel it's important to know when a framework is a good solution, and maybe when it's overkill.

The project is a web gadget previously made using vanilla script and JQuery, It is a part of the "Quicktext" platform and offers an in-app live & customizable messaging widget. We made that remake with React eco-system and Typescript and we're so far happy with results. We gained tons of TS features, React scaling & re-usabilities capabilities and much more!

What do you think?
