In Angular, What is the use for ngDocheck?

Question

Every angular project is required for Redux ? or only required for large applications.

Answer 1

ngDoCheck gets called to check the changes in the directives in addition to the default algorithm. The default change detection algorithm looks for differences by comparing bound-property values by reference across change detection runs.

@Component({selector: 'home-page', template: `...`})
class MyComponent implements DoCheck {
  ngDoCheck() {
    // ...
  }
}
