Dynamic Web Applications: AJAX allows for more interactive and responsive web applications, similar to desktop applications.Server Interaction: It enables seamless communication with the backend server without requiring full-page refreshes.

Data-Centric: AJAX focuses on data exchange rather than entire page updates, reducing server load and improving performance.

Continuous User Experience: Users can interact with the page while data is being processed, providing a more fluid and engaging experience.

Asynchronous Operations: AJAX can handle multiple tasks simultaneously, allowing for nonlinear workflows and improved efficiency.

Advantages of AJAX

Once seen as a luxury for web developers, AJAX has now become a necessity. Here are a few reasons why:

• AJAX is popularly renowned for making websites more interactive and convenient. 
• AJAX enhances the overall performance by allowing the saving or retrieval of data using partial post-backing.
• AJAX has been proven to improve the overall response time.
• Users can benefit from the asynchronous processing feature of AJAX which allows web applications to send and receive data from a web server.
• It can also save bandwidth by focusing on loading specific content rather than the entire content on a page.

While AJAX is a group of technologies being used to develop existing web applications, it has a fair share of limitations as well.

• Anyone can view the source code written for AJAX which makes it less secure than other similar technologies.
• AJAX applications can be seen by the user, but not by the search engine.
• Due to the dynamic web page, it can become challenging to bookmark a specific state of the application. 
• It can make debugging a difficult task for users.
