What is JQuery ?

jQuery is a fast, lightweight, and popular open-source JavaScript library that simplifies client-side scripting for web development. It simplifies many common tasks, such as HTML document traversal, manipulation, event handling, and animation, by providing a unified and easy-to-use API. jQuery abstracts the complexities of JavaScript, allowing developers to write less code while achieving the same functionality across different browsers. It is widely used for creating interactive and responsive web pages and is compatible with various modern web technologies. Although newer web development frameworks have emerged, jQuery remains relevant and widely adopted, especially in maintaining legacy codebases and supporting older browsers.
