What is component in Angular?
Components determine views, which are sets of screen elements that can be selected by Angular. They also can be modified according to your program logic and data.Components use services, which provide specific functionality not directly related to views. Service providers can be injected into components as dependencies, making your code modular, reusable, and efficient.Modules, components and services are classes that use decorators. These decorators mark their type and provide metadata that tells Angular how to use them.The metadata for a component class associates it with a template that defines a view.
