Angular components are the fundamental building blocks of Angular applications, encompassing HTML, CSS, and TypeScript code for reusable UI sections. Defined with the @component decorator, they feature inputs and outputs for data exchange and can utilize various lifecycle hooks. Components support modular design, can be dynamically managed, and facilitate complex UI hierarchies, making them essential for effective Angular development.

1. Get Information about Angular Component
Angular components are the basic building blocks of an
Angular application. They are the building blocks of the UI,
consisting of HTML, CSS, and TypeScript code. Each
component is responsible for a specific section of the UI and is
reusable and modular.
In Angular, a component is defined using the @Component
decorator. This decorator provides metadata about the
component such as its selector, template, styles, and more.
The selector is used to identify the component in the HTML
template, and the template defines the component’s view.
A component can also have inputs and outputs, which allow
data to be passed into and out of the component. Inputs are
specified using the @Input decorator, while outputs are
specified using the @Output decorator.
Components are typically organized into a hierarchy of parent
and child components, with data flowing from parent
components to child components via inputs, and events flowing
from child components to parent components via outputs.

2. Angular also provides various lifecycle hooks for components,
which allow developers to execute code at specific points in the
component’s lifecycle, such as when it is created, rendered, or
destroyed.
Overall, Angular components provide a powerful and flexible
way to build complex, reusable UI components in Angular
applications.

3.  Components are defined in their own files with the
.component.ts extension.
 Components can have their own private CSS styles by
defining them in a separate file with the .component.css
extension. These styles will only apply to the component
and its children.
 Components can also have their own private templates by
defining them in a separate file with the .component.html
extension.
 Components can be dynamically created and destroyed
using Angular’s Component FactoryResolver and
ViewContainerRef APIs.
 Components can be tested using Angular’s built-in testing
utilities, such as Component Fixture and TestBed.
 Components can also be nested within other components,
allowing for the creation of complex UI hierarchies.
 Angular provides several pre-built components, such as
ngFor, ngIf, and ngSwitch, which can be used to simplify
common UI patterns.
 Angular also provides a mechanism for sharing data and
functionality between components using services, which
can be injected into components as dependencies.

4.  Components can be organized into modules, which
provide a way to encapsulate related functionality and
dependencies.
Overall, Angular components are a key part of building Angular
applications, providing a powerful and flexible way to create
modular, reusable UI components.
