What are Annotations in Angular?

Annotations in Angular are metadata that can be added to a class, field, or method to provide additional information about its behavior and capabilities.

These annotations can be used by the Angular framework to configure and manage the components, directives, pipes, and services that make up the application. They are used to define the component's template, style, selector, inputs, outputs, lifecycle methods, and more.

Annotations in Angular are implemented using decorators, which are special functions that can be applied to a class, property, or method. They are a fundamental feature of Angular and play a crucial role in defining the behavior and structure of an Angular application.
