What are nested components?
A nested component is a child of the parent component that contains it. The child component is positioned and rendered relative to that parent. If you use an anchor to attach multiple children to the same side of their parent component, the children will “stack” to create a cleanly aligned header.
What is nested components in angular?
What is a Nested Component? Angular allows us to have a different child, or nested component, which is the same component we normally use in an Angular application. The difference between them is that this child component contains the logic which can be used into the parent component as a single unit.

How are subcomponents installed in a parent component?
In addition to @Module.subcomponents, a subcomponent can be installed in a parent by declaring an abstract factory method in the parent component that returns the subcomponent.
Is the lifetime of a subcomponent bigger than its parent?
Because a subcomponent is created from within its parent, its lifetime is strictly smaller than its parent’s. That means that it makes sense to consider subcomponents’ scopes as “smaller” and parent components’ scopes as “larger”. In fact, you almost always want the root component to use the @Singleton scope.
Why do you use subcomponents in an application?
Another reason to use subcomponents is to encapsulate different parts of your application from each other.
How are subcomponents used in the object graph?
Subcomponents are components that inherit and extend the object graph of a parent component. You can use them to partition your application’s object graph into subgraphs either to encapsulate different parts of your application from each other or to use more than one scope within a component.
