jQuery is a fast, small, and feature-rich JavaScript library.
It makes things like HTML document traversal and manipulation,
event handling, animation, and Ajax much simpler with an easy-to-use
API that works across a multitude of browsers.

With a combination of versatility and extensibility,
jQuery has changed the way that millions of people write JavaScript.<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
