AJAX stands for Asynchronous JavaScript and XML.
AJAX is not a programming language. It is a technique used in web development that allows the browser to communicate with the server without reloading the entire web page.
This makes websites faster and improves user experience.
In traditional websites, every request causes a full page reload.
AJAX removes this problem by sending requests in the background while the page remains active.
After the server sends a response, JavaScript receives the data and updates only the required part of the web page.
This partial update is the main power of AJAX.
AJAX works asynchronously, which means the browser does not stop while waiting for the server response.
Users can continue interacting with the page during data loading.
AJAX is used in almost all modern websites where data needs to be updated dynamically without refreshing the page.
After completing this lesson, you now understand how AJAX communicates with the server and why it plays a major role in modern web development.
