AJAX (Asynchronous JavaScript and XML) is a technique that allows data to be loaded from a server without reloading the entire web page. It enhances the user experience by enabling asynchronous communication between the browser and the server.
Technically, AJAX works as follows:
Client Request: JavaScript sends an HTTP request (via XMLHttpRequest or fetch) to the server without reloading the entire web page.
Server Processing: The server processes the request and responds with data, often in JSON, XML, or plain text.
Response Handling: JavaScript handles the server's response and updates specific parts of the webpage dynamically.
This asynchronous process allows for smooth and interactive user experiences by updating parts of the page without a full reload.
