What is one major benefit of using Ajax in web applications?

One major benefit of using Ajax in web applications is that it greatly improves user experience. Ajax allows web applications to send and receive data asynchronously without having to reload the entire web page. This means that users can interact with the application without interruption, such as submitting forms or updating content dynamically.

For example, when a user submits a form, Ajax can send the request to the server in the background and update only the relevant part of the page with the response. This leads to a smoother and more seamless experience, as users do not see the distraction of page refreshes, and they can continue interacting with other components on the page while waiting for results.

In contrast, increased server load, reduced application functionality, and limitations on data handling do not align with the advantages that Ajax provides. Ajax is specifically designed to enhance interactivity and performance in web applications, making it a favorable choice for developers aiming to create engaging user experiences.
