I'm from VietNam and thank you so much

[@cocomedy2625]

very very gooood, thaaankss maan

[@PhaseControlDNB]

Great example! BTW I think the re-calculation thing can also be avoided by providing a trackBy function for the list items

Thanks. Much learnings

[@MP3D2Y]

Nice video!

[@sergioturizom]

Excellent.

[@SuperLabeled]

Excellent video and incredibly useful! One note, your github example source code doesn't have the ScrollingModule imported and you don't explain adding it to the employee-list module.

[@noalcoholtoday]

Thank you :)

[@hearphone1767]

Hello Minko, thanks for tips! I have a question: but in minute 7:22 you change initialization of variable salesList from EmployeeData[] = Sales to List(Sales) ? where is the difference?

[@tuannguyen-oq4ox]

That makes the object change into immutable. Because the Onpush

[@mahdikamran8061]

Thank you.

[@unnhao]

Nice!

[@Tomkoone]

Thanks for the video :)
Regarding pipes: in such cases when you want to transform a component's method into a pipe because of performance, it's unnecessarily verbose. The pipe won't be used in some other place, but you have to create a separate file, declare it in a module.. Would be simpler if we could just add the directive to the component's method.

[@redsool1]

U can make generic pipe which takes Function as it's arguments as parameters

[@LeonRadley]

Or you could use a setter for the input and calculate the value once in the setter and store it in a separate field

[@pawansahu8605]

Super like to your video, thanks 👍

[@hanche2001]

Please make this a regular thing :)

[@mgechev]

What do you want us to make a regular thing? :)

[@vishalsinghchauhan7413]

Anyone knows about the theme used in edior ? 4:30

[@LeonRadley]

Another one that is important for lists is *ngFor trackBy
Is that still relevant?

[@robby7292]

awesome video. Why does changeDetection act that way though?

[@amals3451]

When I tried to open it doesn't work. It shows the command line interface for one second and it dissappears. Any ideas? Thank you

[@stasberkov]

Can you do a video how to live without zone js? Using Observable-s for template bindings.

[@John69]

awesome :)

[@kairat_ala]

how can improve code without immutable.js ?

[@gillesashley9314]

I want to start with Angular, but considering the future of coding with AI, I'm unsure if I should still go ahead.

[@RajatGuptaOnline]

Where can I good material to learn about change detection, Anyone please suggest

[@christianaustria741]

What does he mean by dropping the browser's frame rate when talking about performance?

[@mgechev]

The browser freezing for milliseconds and creating the perception of suboptimal, laggy user experience.

[@christianaustria741]

@@mgechev got it. Thanks for the explanation and for the wonderful video, I've learned a lot.

[@SeySvK]

timestamps?

[@AlphaFrog1021]

it's in the description

[@SeySvK]

@@AlphaFrog1021 i am glad they added it

[@madeOfClay99]

I thought I knew Angular, but after watching this video, I kind of lost some of my confidence...
So many things I was like, what is that? List import from inmutable? ...

[@mgechev]

Good point! That’s content for advanced use cases. To get started with the framework you don’t need any of this :)

[@sanches620]

i took 2 hours to clone the repository code ;-;

[@mahmoudelkhadragy8154]

same with me not good repo prepared
