The Dependency Inversion Principle use case is great.
The combination of local provider, Injection Token, useExisting and Content Projection is just epic.
Good job Dmytro!

[alexshubin]

Thanks a lot for this video. I'm not a native English speaker but I was very impressed that you managed to explain the Liskov principle much better than I heard in my native language. This is because your explanation was from real life but not from books.

[pastagaz]

Definitely you have to be mentioned in the Angular documentation!
As always, another useful video on your useful YTchannel !

[AndrewRowenko]

Thank you! Very helpful. It is quite challenging to find such a good combination of integrity, consistency and practicality inside one video about Angular. Definitely favorite frontend youtube channel!

[RickyBanerjee]

Not gonna lie, i didn't think i'd learn anything here, but damn the DI Principle was partly new to me. Thumbs Up, thank you for showing me that!

I was looking for something like this. Is kind of hard to understand this concepts but with easy examples as you showed, is just simple ! thanks

[pauloafpjunior]

Amazing video, Dmytro. Do you intend to continue this serie? Talking about architecture styles in Angular, such as CleanArch, will be great.😃

[TheMaltissimo]

Hello, Dmitry!

Could you please add more design pattern videos in context of Angular?

I find your approach extremely useful to understand

[westhack]

Thank you so much. This is all I've been searching for months.

[RSmarza]

Great content! Congratulations 👏👏

Would be great if you create a video about debugging angular memory leaks. 😉 it's an difficult issue to find good references.

[giorgi]

You have made my day!
Thanks a lot.
Cheers from Tbilisi✊🏻

[sourik]

Not sure about Open/Close principle. For me your explanation looks more related to code reusability. I expected smth more parent - child (when child class extends parent) related examples. What do you think?
But explanations of other principles are amazing)
