In what scenarios would using JavaScript over PHP be more beneficial for performance in a webshop setting?

In scenarios where there is a need for dynamic content updates without refreshing the entire page, using JavaScript over PHP can be more beneficial for performance in a webshop setting. This is because JavaScript can handle client-side interactions and update specific parts of the page without needing to reload the entire page from the server. This can result in a faster and more seamless user experience. 

// PHP code for updating a product quantity in a webshop using JavaScript

// Assume we have a form with an input field for quantity and a button to update the quantity
// When the button is clicked, we want to update the quantity without refreshing the page

// PHP code to handle the form submission
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Get the new quantity value from the form submission
    $new_quantity = $_POST['quantity'];
    
    // Update the product quantity in the database
    // This would typically involve SQL queries to update the product quantity
    
    // Return a success message or updated product information
    echo json_encode(['success' => true, 'message' => 'Quantity updated successfully']);
}
