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.
