What are the advantages and disadvantages of using JavaScript with AJAX to handle form submissions in PHP?

When using JavaScript with AJAX to handle form submissions in PHP, the main advantage is that it allows for a smoother and more interactive user experience without having to reload the entire page. This can lead to faster response times and a more dynamic interface. However, one disadvantage is that it may require more complex coding and debugging compared to traditional form submissions. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
  // Process form data here
  $name = $_POST['name'];
  $email = $_POST['email'];

  // Return a JSON response
  $response = array('message' => 'Form submitted successfully');
  echo json_encode($response);
}
?>
