What is AJAX ?
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
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.
