A Component is a building block of an Angular application. It is an independent, reusable, and encapsulated piece of code that is responsible for rendering a specific view and handling user interactions with that view. Components are defined using TypeScript classes and decorated with Angular metadata using the @Component decorator. They consist of a template (HTML), a class (TypeScript), and metadata (decorated with @Component).
Components are used to build and define the UI of an Angular application and provide a way to manage the data and behavior associated with a particular view.
Advantages of Component
Reusability: Components can be reused throughout an application, making development faster and easier.
Modularity: Components allow for modular development, making it easier to maintain and update large scale applications.
Easy Testing: Angular components can be easily tested independently, which helps to improve the quality of the application.
Improved Performance: Angular uses change detection to update the component’s view, which results in improved performance compared to traditional template-driven frameworks.
Better Structure: Components provide a clear structure for an Angular application, making it easier to understand and maintain.
Easy Data Binding: Angular provides two-way data binding, making it easy to keep the component’s view and model in sync.
Easy to Learn: Angular components follow a consistent pattern, making it easy to learn and understand, even for developers with limited experience.
Components is the most basic UI building block of the App. You need to be familiar with combining, using and customizing these basic blocks to be fluent in Angular.
only one component can be instantiated for a given element in a template.

In Angular, a Component is a fundamental building block that controls a patch of screen called a view. Each component combines an HTML template that declares what renders on the page, a TypeScript class that defines behavior, and CSS selectors that determine how the component is used in a template. Components are defined using the @Component decorator, which allows you to specify metadata about the component such as its selector, the URLs for its template and styles.Components play a critical role in Angular's structure, as they provide a way to encapsulate and organize the user interface into manageable, reusable pieces. They also interact with other components and services to bring functionality to your applications.For a detailed guide on creating and using your own components in Angular, you can visit this https://fullstacktutorialshub.com/angular/how-to-create-and-use-your-own-components-in-angular-no-cli/
