What are the potential pitfalls of using JavaScript to refresh content in PHP applications?

One potential pitfall of using JavaScript to refresh content in PHP applications is that it may lead to inconsistent data being displayed to users, as JavaScript operates on the client-side and may not always reflect the most up-to-date information from the server. To solve this issue, you can use AJAX to make asynchronous requests to the server and update the content dynamically without needing to refresh the entire page. 

<?php
// PHP code to handle AJAX request and return updated content

if(isset($_POST['data'])) {
    // Process the data and update the content
    $newContent = $_POST['data'];
    
    // Return the updated content
    echo $newContent;
}
?>
