What are the components in Angular?

In Angular, components are the fundamental building blocks of the user interface. For a specific area of a user interface, a component is made up of HTML, CSS, and JavaScript. These may be thought of as a special HTML element that only Angular understands. Because these components are namespaced by the compiler, styles, and code from one component do not impact other components. The Angular framework then assembles these components to create the user interface for the browser to render.
