Description: A directive in Angular is a class that adds behavior to elements in Angular applications. These directives allow for declarative manipulation of the DOM, facilitating the creation of reusable components and the implementation of presentation logic. There are three main types of directives: component directives, which are the most common and encapsulate both logic and view; structural directives, which alter the structure of the DOM (such as *ngIf and *ngFor); and attribute directives, which change the appearance or behavior of an existing element. Directives are fundamental to Angular’s architecture, as they allow developers to extend HTML with new functionalities and behaviors, thus promoting code reuse and separation of concerns. Proper use of directives can enhance the maintainability and scalability of applications, enabling developers to create more dynamic and responsive user interfaces.
