AJAX is used to improve website performance and user experience.
Without AJAX, every user action such as form submission or button click reloads the entire page.
This creates slow response time and poor interaction for users.
In the above traditional method, the browser sends data to the server and reloads the complete page.
AJAX removes this problem by allowing background communication.
Using AJAX, the page remains active while data is being processed on the server.
Users can continue scrolling, typing, or clicking without interruption.
AJAX allows websites to update only specific sections instead of refreshing the entire page.
This reduces bandwidth usage and improves loading speed.
Modern web applications rely heavily on AJAX for real-time interaction.
This includes login validation, live search, notifications, and dashboard updates.
AJAX also improves user satisfaction because actions feel instant and smooth.
This is one of the main reasons companies use AJAX in almost every web application.
After completing this lesson, you now understand why AJAX is necessary and how it improves modern websites.
