1 - Explain the concept of Angular and its key features: Angular is a client side framework for building dynamic and interactive web applications. Its key features include data binding, dependency injection, and routing.
2) Describe the difference between Angular 1 and Angular 2+: Angular 1 uses a two way data binding mechanism, while Angular 2+ uses a one way data flow. Angular 1 also relies on jQuery for DOM manipulation, while Angular 2+ supports virtual DOM for higher performance.
3) Explain the purpose and usage of TypeScript in Angular: TypeScript is a superset of JavaScript that adds type annotations to enhance code quality, static type checking, and refactoring capabilities.
4) Describe the architecture of an Angular application: Angular applications are structured as modules that encapsulate related components, services, and directives. Components are responsible for displaying the UI, services manage data and logic, and directives enhance the behavior of DOM elements.
5) Explain the concept of dependency injection in Angular: Dependency injection allows you to create and pass objects to other classes or components automatically. This helps to improve code reusability, maintainability, and testability.
6) Discuss the difference between services and factories in Angular: Services are singleton objects that are shared across the application, while factories create new instances each time they are requested.
7) Explain the purpose and usage of directives in Angular: Directives extend the HTML syntax with custom attributes or elements. They can be used to encapsulate functionality, create custom components, or enhance the behavior of existing elements.
8) Describe the different Angular routing strategies: Angular provides support for different routing strategies, including hash based, path based, and component based routing. Each strategy has its own advantages and disadvantages.
9) Discuss the concept of modules in Angular: Modules in Angular organize code into cohesive units and provide a way to isolate different parts of the application. They can be used to group related components, services, directives, and pipes.
10) Explain the role of pipes in Angular: Pipes are used to transform, filter, or format data in templates. They can be used to manipulate strings, numbers, dates, and other types of data.
11 - Describe the best practices for managing state in Angular applications: Angular applications use a combination of state management techniques, including component state, services, and NgRx.
12) Discuss the importance of testing in Angular applications: Testing is crucial for ensuring the stability and reliability of Angular applications. Unit testing, integration testing, and end to end testing are essential for covering different aspects of the application.
13) Explain the purpose and usage of RxJS in Angular: RxJS is a library for reactive programming in JavaScript. It is used in Angular to manage asynchronous events, such as HTTP requests, user interactions, and data streams.
14) Describe the concept of server side rendering (SSR) in Angular: SSR is a technique that allows Angular applications to be rendered on the server before being sent to the client. This can improve performance and SEO.
15) Discuss the advantages of using Angular Universal: Angular Universal is a tool that enables SSR for Angular applications. It provides a way to create fully functional Angular applications that can be deployed on Node.js servers.
