What are some best practices for maintaining separation between PHP and JavaScript code in web development?

To maintain separation between PHP and JavaScript code in web development, it is recommended to use a templating engine like Twig or Blade to keep the presentation logic separate from the business logic. This helps in organizing the codebase and making it easier to maintain and scale. 

// Example using Twig template engine
$loader = new \Twig\Loader\FilesystemLoader('/path/to/templates');
$twig = new \Twig\Environment($loader);

echo $twig->render('index.html', ['data' => $data]);
