What is a key feature of Angular components?

Components have no associated HTML files
Components must have a selector
Components cannot have styles
Components are defined using traditional JavaScript

The correct answer is: Components must have a selector

A key feature of Angular components is that they must have a selector. The selector is a crucial part of a component as it allows you to define a custom HTML tag that can be used within templates to instantiate the component. This enables the creation of reusable and modular parts of an application, allowing developers to build complex user interfaces more efficiently. By defining a selector, developers can easily integrate components into their application, promoting component-based architecture. The use of selectors not only enhances readability but also provides a clear structure for how components are utilized throughout the application. The other options lack essential characteristics of Angular components. Components can indeed have associated HTML files or inline templates, they can also include styles (both inline and external), and they are generally defined using TypeScript, which is a superset of JavaScript designed for developing large applications.
