The nice thing is that when you open your component you immediately see which Services are injected, which functions of those services are called and what is returned by those functions.

All children inherit some characteristics from their parents and use that in their life.

You almost always have to find a middle ground there. While things could become quite flexible and reusable you have to go trough multiple files to get an understanding of what is actually happening. What you see is what you get could be achieved by placing your code in a Service or a utility file. Inheritance is a way to extend your code with functionalities from other code. For you who dont know what inheritance is. Basically the same as parents with their children. However more code is not necessarily bad, especially in this case, as the above solution helps you to make your code easier to understand. The takeaway should be that code should be written in a way that it has the highest form of re-usability, maintainability and understandability. This means each modal will be a separate component as the template is too different to put everything in one component. As the inheritance is only one level deep and this is an easy example, its still sort of manageable. You can then call the Service from your Component which does the work for you. Code reusability is good as this also increases maintainability. The Observable isnt an Angular specific feature_medium.com, Understanding hot vs cold Observables_When i started to get the hang of Observables it took me quite some time to understand what is meant by a hot or a cold_medium.com, Understanding RxJS map, mergeMap, switchMap and concatMap_Mapping data is a common operation while writing your program. If you know the kid without knowing the parents you might not be able to place some characteristics. #10- The Best Online Platforms to Learn Something New, Today! When developing your applications you inevitably come across situations where you need to create functionalities/features or even functions which are similar, but spreaded over multiple components or even modules. In Angular, and Javascript applications in general, there are many patterns and solutions to set this up. If you open the modal-companies.component.ts you dont immediately see this all this logic. I bet it will be a lot harder to see how everything works as methods could potentially be called multiple levels deep and you really have to dig in to see where everything is and how it all correlates. #13- Apple CarPlay Not Working? The modal components use inheritance to encapsulate reusable modal logic. In the example below we have a situation where we need to display multiple models with different unmappable datasets. And in my opinion, understandable code is good code. Why is it a problem then? As i mentioned earlier, you probably do this to increase code reusability. - Here's How to Fix Common Issues, #16- The Batman Arkham Games in Chronological Order, #17- What is ERC-3475?

Anyway, always remember: Understanding, creating and subscribing to observables in Angular_When version 2 of Angular came out, it introduced us to observables. In that respect, i described a different solution which might suits your needs. As Angular is entirely Class based, inheritance could be a solution. For you as the author everything might be perfectly clear, but will it still be clear after a few months? But things become really hard when you go into multiple levels of inheritance and logic gets more complicated. Inheritance itself is not bad. Just like class inheritance has a drawback, the above solution also has a drawback and that is that you have to write more code. You would have to do dig in and see or meet the parents in order to understand why the kid is what it is. well, Inheritance results in abstracting away implementation details. #12- What is One Hot Encoding? And what if another colleague, or worse, a new colleague picks up the code.

Now, what i really like about this approach is that when you open one of the component files, you immediately see what functionalities that component has en where you can find it. As you can see we have removed the inheritance and moved the code that was in the modal.ts class to the modal-helper.service.ts service. If you would refer back to my example about the child that inherits characteristics from their parents, it works exactly the same. You could think of filtering, sorting, managing selections, saving etc. While this is a somewhat opinionated post. Heres why that might not be the best solution. This is why I prefer a, more declarative, what you see is what you get solution over class inheritance. In the ideal world, you want to quickly see/scan it, understand it, fix your stuff and move on.
