Change Detection Strategy in Angular

Angular Change Detection is how angular achieves all its cool features. The two way binding in angular is possible due to the change detection by Angular. The default change detection will runs on all child components if something changed in the parent component, and that can cause a performance issue if you have a big component tree.
To avoid that we can use OnPush change detection strategy and ChangeDetectorRef and we can ask angular when to run the change detection, so this can improve the application performance.

[TranNguyen-pwxo]

hello, can you tell me what's the different between markForCheck abd detectChanges?

[mounicanagasri]

this was ok you could have explained reattach and checkNoChanges methods in usage of changeDetectetorRef

[amguruprasath]

This was a blessing. Man, please teach us how to develop and write professional Angular application.

[Karthikp]

You should explain the code first. If we see only parent child printed in console, how can we understand

[mabos]

on puss... wow I struggeled to understand that this meant on PUSH...
anyway so what to do with the array.push you didn't explain the last part
should we do the markForCheck again?

thanks

Pl upload some videos regarding angular lifecycle

[abdullahtahan]

note that this strategy applies to all child directives and cannot be overridden so that's why when apply to parent we no longer get the changes
