Summary of Angular HR Interview Questions

This tutorial provides a comprehensive guide for individuals preparing for job interviews focused on Angular, a popular web application framework. It covers common questions and key concepts that candidates may encounter.

Key Concepts

  • Angular Framework: A platform and framework for building single-page client applications using HTML and TypeScript.
  • Components: The fundamental building blocks of Angular applications, each controlling a part of the user interface (UI).
  • Modules: Containers for a cohesive block of code dedicated to an application domain, workflow, or closely related capabilities.
  • Services: Classes that handle data logic and business rules, typically used for sharing data across components.
  • Dependency Injection: A design pattern that implements Inversion of Control (IoC), allowing Angular to provide instances of services to components.
