In PHP e-commerce, how do I manage dependencies?

            // Example of managing dependencies in a PHP e-commerce application
            require 'vendor/autoload.php'; // Load Composer dependencies

            use Some\JavaScript\Library; // Example JavaScript library usage

            // Function to handle dependencies
            function manageDependencies() {
                // Check and load necessary dependencies
                if (!class_exists('Library')) {
                    throw new Exception('Required library is missing.');
                }

                // Use the library
                Library::init();
            }

            manageDependencies();
