Difference between createEmbeddedView and createComponent in Angular.

import { Component, ViewContainerRef, ComponentFactoryResolver, NgZone, VERSION, ViewChild } from '@angular/core';

@Component({
  selector: 'hello-world',
  template: `<h1>Hello world!</h1>`,
  styles: [``]
})
export class HelloWorldComponent  {}

@Component({
  selector: 'my-app',
  template: `
      <ng-container #hw></ng-container>
  `,
  styles: ['']
})
export class AppComponent {

  @ViewChild('hw', {read:ViewContainerRef}) vc: ViewContainerRef;

  constructor(private resolver: ComponentFactoryResolver) {}

  ngOnInit() {
    const factory = this.resolver.resolveComponentFactory(HelloWorldComponent);
    this.vc.createComponent(factory);
  }
}
