at 35:17, getting all the data at once is not good for performance, segregating into API is a better approach.

At 21:39 I could just create simple classes like Bank1, Bank2, why add adapter to them?

@ehSamurai3483 Ай бұрын

For the problem 2:32 the strategy pattern can also be used.

@ehSamurai3483 Ай бұрын

It resembles an observer pattern. like the mediator has a signal method and all the devices are kind of subscribed to that mediator.

@levonog Ай бұрын

Yeah, kind of, but in the observer, the subscribers should not be able to communicate to each other. This is the main difference of these patterns

@ehSamurai3483 Ай бұрын

@@levonogAt 0:37 it's mentioned that there is no direct communication between objects, so it's the same in the mediator pattern?

Hi! Really love your videos, very understandable and nice to watch. I think that in this example a removePartN() group of methods should be added to the builder interface, otherwise it would be impossible to remove products form a pizza after being added, or am I missing something?

@nanonkay5669 2 ай бұрын

It's apparent early on that understanding interfaces is key, crucial, paramount and fundamental to implementing design patterns. Interfaces are at the heart of being good at designing software

@levonog 2 ай бұрын

You are totally correct!

@Alticroo 2 ай бұрын

How does the adapter pattern differ from strategy? It seems like the goal is to standardize the interface across external systems in both cases.

@levonog 2 ай бұрын

Hello! Strategy is a different pattern, it helps to have a family of interchangeable algorithms. You can watch the video on the channel about the Strategy pattern :)

Great video! can we get an in-depth series for each design pattern? with examples of before and after code, refactoring, and combining one or more design pattern for each solution.

@levonog 2 ай бұрын

This course took me 8 months and right now I want to take a break from design patterns and concentrate on system design, but who knows, maybe in the future :)

Yes, but how can I type this using enum, if the object keys will only have 2 properties (apple and orange), and not all the keys of enum?

@gerda-morozova 3 ай бұрын

I argee with this

@levonog 3 ай бұрын

Yeah, you can’t do this if you don’t want to use all the enums. But there are other solutions, for example, you can create another enum, or you can use Extract built-in type to extract needed enums.

Kudos on the really high-quality presentation, though tbh we don't really need a specific OO design pattern for creating a set of stages. This is more of a specific implementation for a use case than a design pattern. It can probably be naturally created by a developer who's thinking about requirements like going to the next or previous stage, or jumping to a specific stage.

@levonog 3 ай бұрын

Yes of course, this example is for demonstration purposes only. I felt that this example was the best way I could tell about this design pattern, so I chose it. BTW, thanks for the comment, really appreciate it!
