You’re not wrong, but newer version of the language have steered devs away from these quirks. The quirks remain because the JavaScript language is 100% backwards compatible. It’s fun to laugh at these quirks, but I’ve been a full time JavaScript developer for 4 years and part time since 2015, and I’ve never seen any of these quirks come up in the real world. If you tell your developers to use === instead of == in code review, you eliminate most of the problems imo.

JavaScript tooling deserves more hate imo. The ecosystem is kinda a disaster, but Vite is making a lot of progress in fixing that. If you ignore React Native and metro bundler, I think the state of web is looking pretty optimistic right now. At least from a technology perspective. From a business/AI/enshitification perspective we’re cooked lol
