What is Angular? 

Angular is a web framework. It is used by several companies and organizations in web applications. It’s been around since the late 1990s, but it’s been around for a while. Although angular is used widely in today’s businesses, its foundation is a set of technologies that initially existed in JavaScript and at the time of its creation, namely Node.js, a robust open-source front-end JavaScript framework, browser, and language platform.

How familiar are you with Angular? 

The interviewer may ask you this question to gauge your familiarity with the framework. You might include an example of how you implemented Angular in your past jobs in your answer. If so, you are probably in the early stages of the project’s maturity cycle. If you’re not, you’ve probably spent years building frameworks—or building whatever your domain is now. It may be that you’ve completed the framework and are ready to move on to other topics. You may also have a very specific project in mind that requires you to use one or more other technologies.

What is Angular used for? 

AngularJS is the foundation of the popular JavaScript and HTML frameworks. It’s used to build HTML and CSS websites. You can write your HTML, CSS, JavaScript, and web applications without understanding the underlying technologies. It is all about using the Angular framework and its libraries to build web applications. Suppose you’re just getting started using web development frameworks like Angular or Bootstrap. In that case, it might take you a few s to get comfortable with the framework, so if you find you need to jump in and add more features to your application, you might not be able to use everything you think you need. 

The important thing to understand in terms of web development frameworks is that different frameworks like Angular don’t provide the same set of benefits; these frameworks provide different levels of automation, which can lead to different levels of complexity. So, if you decide to learn the best web development frameworks for your needs, be sure you do research. 

What’s the difference between Angular and AngularJS? 

To begin with, there is no difference at all. AngularJS uses a slightly different language and provides the same functionality. However, the technology behind it is the same, so it is often referred to as AngularJS 2.x. There are, of course, two different styles of the Angular 2 tool kit. One is the directive-oriented style that is built around directive messages. Angular is used in combination with directives. Express, a widely used component library for JavaScript, provides the components required to create the reactive architecture. It can be used in various applications, including Web 2.0 applications and systems that need full-blown application integration, e.g. social network sites. It can be seen as an integration layer between Java and the C# programming language with a large-scale integration with the existing Java infrastructure. 

Can you describe what scope is in Angular? 

The interviewer may be gauging your understanding of how models are developed within Angular with this question. The second question asks you to describe the process and constraints behind the design process. The third and final question asks if you have any other business considerations regarding the application you have developed. We hope you find this questionnaire useful in understanding the need for data-driven decision support in the organization. As stated earlier, the questionnaire was developed to provide your organizational context. 

What does data binding refer to? 

The interviewer may want to know how experienced you are with the main operating features of the Angular framework. You might answer with a brief definition of data binding along with your understanding of its importance in the application.” Data binding can be one of the most important features of Angular. This is because data binding allows for communication between the DOM that you’re developing and the components, and it consists of four main forms. The forms are two-way, property, event and string interpolation data binding.” 

Can you tell me what directives are in Angular? 

The interviewer might ask you this question to see if you know the differentiation between directives and components in Angular. It would be best to briefly define what directives were and highlight how a directive might work within a DOM element with directives. In the next section, we highlight that the application logic does not follow the definition provided by the Directive but that you must first define the data model of the Directive. We’ll demonstrate why this is important. A directive definition is part of the Angular 2.0 directive generation syntax, so you must use the same syntax for now. You can find the complete definition of Directive. A directive in the Document Root of the angular2 file.” Directives in Angular work to connect a specific behaviour to various elements within the DOM”. 

What is NgModule? 

This question can allow the interviewer to understand better your knowledge of using the Angular application. You might include your personal experience with using NgModule to bootstrap and launch various applications in your answer. This knowledge can establish communication between you and the interviewer that you have successfully navigated the process of creating an Angular application. NgModule is a cross-platform component library for creating custom modules using node.js for an application. The library creates a module that will interact with an application on a particular platform and with the application on another platform. When you create a module using the module registry, it is used to upload the module, download the module’s source code, and integrate it into the application. 

What are filters used for in Angular? 

You can include examples of how filters are used and how they work, and if you have experience working on specific projects where you created custom filters for a DOM, you can also highlight this in your answer. Finally, to wrap this up, we highlight two areas where knowledge of Web technologies can be useful. First, notice we used technologies outside typical domain expertise (we used CSS in this example) or might not use (we didn’t use Java in this example, but that would be useful information to know!). We used these technologies to implement the filter. Second, we included several resources—both tutorials and online resources—to get you started. 

Filters specify which variables are available in the scope of an object. A user can define which variables in a service should be made available at the application level or available to the users via an action. , you will learn about the syntax, structure, and role of each of the components in the angular module, and you will be able to use them to implement some of the data models of your application. You will see that the default action is to save in the next. To enable or disable saving, change the SaveAction attribute of the template in ASP.NET and then save the modified configuration using the SaveAs method. Next, you will learn about the .NET Framework and learn about .NET components—such as property and delegate types—and how they are accessed in Visual Studio. 

Tips for preparing for your interview 

Tips can help you prepare for your Angular interview: 

  • Stay up-to-date with various programming languages, including JavaScript, TypeScript, and HTML coding, as working within Angular can require different language applications. 
  • Consider researching the company you are interviewing for to determine what kinds of projects and applications the company completes that can benefit from using the Angular framework. 
  • Consider preparing to demonstrate your skills and knowledge through a practical test, as some interviewers might use real-life applications to test your programming abilities. 

  • The best tip is to practice answering Angular interview questions with your friends, family, or other close acquaintances to help you practice how you will answer each question.
