Introduction
jQuery is a fast, small, and feature-rich JavaScript library. It simplifies HTML document traversal and manipulation, event handling, and animation. Learning jQuery is easy if you already know a little bit of JavaScript. The significant advantage of jQuery is that we do not need to worry about browser support, and the code will run exactly the same in all major browsers.
Further Explanation:-
It is free, open-source software using the permissive MIT License. Currently, jQuery is used by 77% of the 10 million most popular websites. 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.
Uses of jQuery:-
Its syntax makes it easier to navigate a document, select DOM elements, create animations, handle events, and develop Ajax applications.
It also provides capabilities for developers to create plug-ins on top of the JavaScript library.
It enables developers to create abstractions for low-level interaction and animation, advanced effects, and high-level, theme-able widgets.
The modular approach to the jQuery library allows the creation of powerful dynamic web pages and Web applications.
