What are the Components of Angular?

This article describes the Components of Angular.

Components are a key building block of Angular applications. They are responsible for organizing the application into reusable, self-contained parts. Each component has its own view, which is typically defined using HTML and CSS, and its own logic, which is typically defined using TypeScript.

In Angular, a component is defined using a TypeScript class that is decorated with the @Component decorator. The decorator provides metadata for a component, such as its selector (which is used to identify the component in the HTML), its template or templateUrl (which defines the component’s view), and its styles or styleUrls (which define the component’s styles).

A component can also have input and output properties, which allow it to communicate with other components. Input properties are used to pass data into a component, while output properties are used to emit events out of a component.

Components can be nested inside other components, creating a hierarchical structure of components that represents the structure of the application. This makes it easier to manage complex applications and promotes code reusability.

Overall, components are a fundamental concept in Angular and are used extensively in building Angular applications.
