I've casually seen this issue

you don't need a js library to attach an event listener
to some elements ... you can use vanilla JS, for example:

const elements = document.querySelectorAll("<selector>");

elements.forEach(function(elem) {
    elem.addEventListener("click", function(event) {
        // ...
    });
});
