Essential Computer Terminology for Angular Development

Essential Computer Terminology for Angular Development

This resource provides a comprehensive glossary of essential computer terminology related to Angular and web development. Understanding these terms is crucial for beginners who wish to grasp the foundational concepts of Angular and programming.

Key Concepts

1. Angular

  • A popular framework for building web applications using HTML, CSS, and TypeScript.
  • Provides tools for creating dynamic and responsive user interfaces.

2. Component

  • A reusable building block of an Angular application.
  • Each component has its own template, styles, and logic.
  • Example: A user profile component displaying user information.

3. Directive

  • A class in Angular that can modify the behavior or appearance of elements in the DOM.
  • Types:
    • Structural Directives: Change the structure of the DOM (e.g., *ngIf, *ngFor).
    • Attribute Directives: Change the appearance or behavior of an element (e.g., ngClass, ngStyle).

4. Module

  • A container for a cohesive block of code dedicated to an application domain, a workflow, or a closely related set of capabilities.
  • Angular apps are modular and use NgModules to organize the application.

5. Service

  • A class that provides specific functionality not tied to a particular view or component.
  • Commonly used for data retrieval and sharing data among components.

6. Dependency Injection

  • A design pattern in Angular that allows a class to receive its dependencies from external sources rather than creating them itself.
  • Promotes code reusability and easier testing.

7. Routing

  • The mechanism for navigating between different views or components in an Angular application.
  • Managed by the Angular Router, enabling single-page application (SPA) behavior.

Conclusion

Understanding these terms is essential for anyone starting with Angular. By familiarizing yourself with the above concepts, you'll be better prepared to build and maintain Angular applications effectively.
