What advantages do we get from abstract entities in our app?

👨‍🎓 It is easy to understand: you see all dependencies of your entity in its constructor

🧞 It is easy to test: you can just mock any of your dependencies to test

🧩 It is easy to reuse: your components and directives can be used in any context if it has dependencies that they need to be created

♻️ It is environment agnostic: you can start your app in SSR or other environments (see also @ng-web-apis/universal)
