1 - What is Angular?
Angular is a popular JavaScript framework used for building dynamic and interactive web applications. It follows the Model View Controller (MVC) architectural pattern and provides a comprehensive set of tools and features for efficient development.
2) Explain the key features of Angular.
Angular offers features like two way data binding, modularity, dependency injection, built in validation, and extensibility through directives and components.
3) What is a module in Angular?
A module in Angular organizes related functionality and encapsulates services, directives, components, and other artifacts into a logical unit.
4) Describe the role of components in Angular.
Components are the building blocks of Angular applications and encapsulate a view, template, and associated logic. They enable reusable and maintainable code.
5) Explain the difference between a directive and a component.
Directives extend HTML with new attributes or behaviors, while components are more comprehensive and encapsulate complex functionality with a view and associated logic.
6) What is the purpose of dependency injection in Angular?
Dependency injection manages object creation and wiring, ensuring that services and other dependencies are automatically injected into components and directives.
7) Describe the change detection mechanism in Angular.
Angular employs a change detection mechanism that tracks changes in application state and intelligently updates the UI as needed.
8) Explain the difference between ngOnInit() and ngAfterViewInit() lifecycle hooks.
ngOnInit() is called once the component is initialized and inputs are set, while ngAfterViewInit() is called after the component's view is fully initialized and rendered.
9) What are the benefits of using Angular for application development?
Angular provides increased productivity, reduced development time, code reusability, and improved testing capabilities.
10) Describe the concept of server side rendering in Angular.
Server side rendering generates the HTML on the server before sending it to the client, resulting in faster initial page loads.
11 - What are some common performance optimization techniques in Angular?
Optimizations include using change detection strategies, lazy loading modules, and utilizing performance monitoring tools.
12) Explain the role of RxJS in Angular.
RxJS is a reactive programming library included in Angular that provides advanced observable patterns for managing asynchronous data streams.
13) Describe the process of creating and using custom pipes in Angular.
Custom pipes transform data values and are created using the @Pipe decorator. They can be applied to HTML expressions to manipulate data before display.
14) What are the best practices for Angular component design?
Component design best practices include separation of concerns, encapsulation, encapsulation, and unit testing.
15) Explain the concept of Angular Router.
Angular Router is a built in routing mechanism that manages navigation between different views and components in an application.
