Asynchronous communication means tasks can run in the background without stopping the main program.
In web development, this allows the browser to continue working while waiting for data from the server.
In asynchronous behavior, the browser does not wait for one task to finish before moving to the next.
This helps create faster and smoother user experiences.
AJAX uses asynchronous communication to send and receive data from the server.
This prevents the page from freezing while data is loading.
The third parameter set to true enables asynchronous mode.
This means the request runs in the background.
Asynchronous communication is essential for modern websites such as dashboards, chat systems, and live search.
After completing this lesson, you should clearly understand what asynchronous communication is and why AJAX depends on it.
