What are the potential pitfalls of using JavaScript to count user clicks on a website?

One potential pitfall of using JavaScript to count user clicks on a website is that it relies on client-side data, which can be easily manipulated by users. To ensure accurate and secure click tracking, it is recommended to use server-side scripts, such as PHP, to handle the counting of clicks. 

<?php

// Check if a click has been made
if(isset($_POST['clicked'])) {
    // Increase the click count
    $file = 'click_count.txt';
    $current_count = (int)file_get_contents($file);
    file_put_contents($file, $current_count + 1);
}

// Display the click count
echo "Total Clicks: " . file_get_contents('click_count.txt');

?>
