What is AJAX and how does it enhance user experience on a web page?

AJAX stands for Asynchronous JavaScript and XML. It is a technology used to send and receive data from a web server without having to reload the entire web page. This allows for faster and more dynamic interactions on a web page.

By using AJAX, web pages can update content dynamically without requiring users to wait for a full page reload. This enhances user experience by providing a more seamless and interactive browsing experience.

For example, with AJAX, form submissions can be validated in real-time without refreshing the page, search results can be displayed instantly as the user types, and new content can be loaded without interrupting the user's current activity on the page.

Overall, AJAX helps in improving the speed, responsiveness, and usability of a web page, leading to a more engaging and user-friendly experience.
