What are the main benefits of using vanilla JavaScript in Bootstrap 5.3

The primary benefit of Bootstrap 5.3's shift to vanilla JavaScript is improved performance due to the removal of the jQuery dependency, resulting in faster page load times and a more streamlined user experience. This also allows for a more modern JavaScript development workflow, aligning with current web development standards. Additionally, it reduces the overall file size of Bootstrap, contributing to a leaner and more efficient framework.
