Inside Constructor what is the use of inject decorator

When I'm reading the blog about dynamic component creation, I have seen the below inject decorator inside the constructor.

constructor(@Inject(ComponentFactoryResolver) factoryResolver) {
    this.factoryResolver = factoryResolver
}

Why we are injecting like this? Can any one please explain.

It means that angular will handle automatically and internally the instance creation for the factoryResolver.

In latest versions of angular you don't need to specify the @Inject in the constructor, nor the assign to this.factoryResolver:

constructor (private factoryResover: ComponentFactoryResolver) {}
