view object in Angular -> In simple words, it is some internal object that represents an Angular template.

LView, TView.data

The LView array contains data describing a specific template and in TView.data Angular keeps the information that is shared across templates

Cumulative and template bloom filters

  • Root component always creates NodeInjector on root view
  • Angular creates NodeInjector on any tag that matches Angular component or any tag on which we’re applying a directive
  • Providers and viewproviders defined on Component/Directive also create NodeInjector if it has not been created yet

special objects: ChangeDetectorRef, ElementRef, TemplateRef, ViewContainerRef, Renderer2
