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.
jQuery is like by the developers because of its simplicity and cross-browser compatibility. The clean and simple syntax of jQuery facilitates interactions with DOM elements on web pages. Developers can create beautiful animations and effects without devoting a lot of time to learning these skills. jQuery is desirable because it is lightweight, there are no unusual functions, they are moved to plug-ins, so if needed, you can easily add any function.
