What is Ajax and how does it work?

Ajax stands for Asynchronous JavaScript and XML. It is a set of web development techniques used to create asynchronous web applications. Ajax allows web pages to send and receive data from a server in the background without interfering with the display and behavior of the existing page.

When a user interacts with a web page that uses Ajax, the page can dynamically update content without needing to reload the entire page. This results in a more responsive and interactive user experience.

Ajax works by making asynchronous HTTP requests to the server using JavaScript and handling the responses to update the page content dynamically. This allows for dynamic content loading, form submissions without page reloads, and real-time data updates without disrupting the user experience.

Overall, Ajax plays a crucial role in modern web development by enhancing user interactions and providing a smoother browsing experience.
