JavaScript minification breaks WooCommerce add-to-cart functionality

JavaScript minification conflicts with WooCommerce’s core JavaScript functionality. Minification plugins alter critical WooCommerce scripts like cart-fragments.min.js, breaking AJAX operations required for dynamic cart updates. The minification process reorders script execution, preventing WooCommerce scripts from loading before required dependencies.

Variable and product types are handled incorrectly due to complex JavaScript logic being altered by minification. Over-aggressive minification strips critical comments or alters syntax that WooCommerce relies on. Theme and plugin scripts added via functions.php or other plugins create conflicts with the minified WooCommerce code, further exacerbating the issue.
