The modular approach to the jQuery library allows the creation of powerful dynamic web pages and Web applications. This enables developers to create abstractions for low-level interaction and animation, advanced effects and high-level, theme-able widgets. jQuery also provides capabilities for developers to create plug-ins on top of the JavaScript library.

JQuery's syntax is designed to make it easier to navigate a document, select DOM elements, create animations, handle events, and develop Ajax applications.

Web analysis indicates that it is the most widely deployed JavaScript library by a large margin, having at least 3 to 4 times more usage than any other JavaScript library. As of Aug 2022, jQuery is used by 77% of the 10 million most popular websites. It is free, open-source software using the permissive MIT License. JQuery is a JavaScript library designed to simplify HTML DOM tree traversal and manipulation, as well as event handling, CSS animation, and Ajax.
