Angular is a JavaScript-based front-end framework for building web applications. It uses a component-based architecture to manage the rendering and behavior of the user interface. The core concepts of Angular include:
- Components: Building blocks of the user interface, each having its own template, logic and styles.
- Modules: Collection of related components, services, and directives.
- Template: A declarative representation of the component’s view, written in HTML.
- Data Binding: Two-way synchronization of data between the component class and the template.
- Directives: Structural or attribute directives used to modify the DOM based on application logic.
- Services: Reusable components responsible for providing data and logic across the application.
Angular uses these building blocks to create a dynamic, scalable, and maintainable application. It also provides features such as dependency injection, observables, and change detection to manage state and data flow within the application.
