AJAX libraries are a set of JavaScript functions that allow developers to make asynchronous requests from the client-side. They are used in frontend development to create dynamic webpages and applications. AJAX libraries provide an easy way for developers to send and receive data without having to reload the page, making it easier for them to create interactive user experiences. To use an AJAX library, developers need to include the library's script tag in their HTML document and then call its functions when needed.
