AJAX Applications

Summary
AJAX is used in many real-world web applications: live search suggestions, content uploads increase as you scroll, form validation without reloading, updated shopping cart numbers, to real-time chats. Good implementation always pays attention to the status of the request, the handling of the error, and the loading feedback so that users are not confused. With AJAX, pages feel like desktop apps because only the data moves through the network.
Key points
- Common examples: live search, infinite scroll, and asynchronous form validation
- AJAX makes the page responsive because only the data is sent
- Loading status and error handling are important for user experience
- Back button behavior and history should be noted in the AJAX application
- Accessibility must be maintained so that the user of the screen reader remains comfortable
