How can one ensure that JavaScript classes are properly loaded in PHP applications?

To ensure that JavaScript classes are properly loaded in PHP applications, you can use the `wp_enqueue_script()` function provided by WordPress. This function allows you to enqueue JavaScript files in a way that ensures they are loaded in the correct order and only once. By specifying dependencies for your scripts, you can make sure that any necessary JavaScript classes are loaded before your custom script runs. 

// Enqueue JavaScript file with dependencies
function enqueue_custom_script() {
    wp_enqueue_script('custom-script', get_template_directory_uri() . '/js/custom-script.js', array('jquery', 'other-script'), '1.0', true);
}
add_action('wp_enqueue_scripts', 'enqueue_custom_script');
