1 - What is the difference between components and directives in Angular?
Components are reusable UI blocks with a template, data, and logic, while directives are for modifying the behavior or appearance of HTML elements.
2) Explain the concept of dependency injection in Angular.
Dependency injection is a design pattern that allows you to request objects from a container that will provide them to you. This makes it easy to manage dependencies and decouple components.
3) How does Angular handle routing?
Angular uses a router to manage navigation between different components. The router is responsible for determining which component should be displayed at any given time.
4) What are the different types of data binding in Angular?
One way, two way, property, and event binding are the different types of data binding used to sync data across the HTML template and the component logic.
5) Explain the change detection mechanism in Angular.
Angular uses a change detection mechanism to keep track of changes in the application and update the UI accordingly. This ensures that the UI is always up to date with the latest data.
6) How do you handle errors in Angular?
Angular provides a try catch block mechanism to handle errors in components. You can also use error handling services to log errors and perform other actions.
7) What is the purpose of the ngOnInit lifecycle hook?
The ngOnInit lifecycle hook is called when a component is initialized. It is commonly used to perform tasks such as initializing data or subscribing to events.
8) How do you improve performance in Angular applications?
Use change detection strategies, lazy loading, and caching to enhance performance. Additionally, you should minimize DOM operations and avoid excessive data binding.
9) Explain the concept of zones in Angular.
Zones provide a way to encapsulate asynchronous operations and handle exceptions. They ensure that changes made within a zone are detected and reflected in the UI.
10) What are the benefits of using the Angular CLI?
The Angular CLI simplifies development by creating projects, generating code, and providing utilities for testing, building, and deploying applications.
