What role does jQuery play in simplifying the process of executing shell commands through PHP on a website?

When executing shell commands through PHP on a website, the process can be simplified by using jQuery to make asynchronous requests to a PHP script that handles the execution of the shell commands. This allows for a smoother user experience as the commands can be executed in the background without causing the webpage to reload.

<?php
// PHP script to execute shell command
$output = shell_exec('your_shell_command_here');
echo $output;
?>
