Crack Angular Interview with the Most Expected Interview Questions in 2022

Preparing day and night for your dream job as an Angular developer? If so, then we are here to help you out with our ultimate Angular interview cheat sheet. Let’s get you started without any fuss or delay:

Question1: What is Angular?

Answer: Developed and maintained by Google, Angular is a TypeScript-based open-source web application framework. It ensures developers with an intuitive yet powerful framework to develop front-end web-based applications. Dependency injection, end-to-end tooling, and declarative templates are its top inbuilt features, facilitating web application development.

Question2: Why was Angular introduced as a client-side framework?

Answer: There was a time when VanillaJS and jQuery ruled over developers for developing dynamic websites. But, as the sites became more abrasive, scalable, and complex due to new functionalities and features, it became challenging for developers to keep up with the code advancement with the conventional programming methods. Also, developers were in great demand of data handling facilities when dealing with jQuery. This was the time when Angular made its debut and took the whole development market by storm. It helped developers to address issues while allowing them to easily segregate code into smaller bits of information, vernacularly known as Components in Angular. Angular, the Client-side framework ensures developers work on advanced web applications like SPAs which, if developed by jQuery and VanillaJS, is a time-taking process.

Question3: Define the ng-content Directive?

Answer: Traditional HTML elements have some content between the tags. For example;

<p>Put your paragraph here</p>

Now, look at the below example of having custom text between angular tags:

<app-work>This won’t work like HTML until you use ng-content Directive</app-work>

Obviously, this won’t work as it worked for HTML elements. To make it function, you will have to leverage the ng-content Directive. Moreover, it allows developers to reuse components.

Question4: What are the various features of Angular.

Answer: Below is the top reasons why developers prefer Angular over front-end JavaScript framework:

Accessibility Applications

The framework ensures efficient development of accessible applications backed with ARIA-enabled components, developer guides, and inbuilt a11y test infrastructure.

Angular CLI

Angular offers optimum support for command-line interface tools to add components, instant deploying, testing, and many more.

Cross-Platform App Development

This framework has the potential to develop efficient and powerful desktop, native, and progressive web applications. It offers optimum support to create native app development via NativeScript, Cordova, or Ionic. From developing high-performance, offline, to zero-step installation progressive web apps, developers leverage modern web platform features of Angular. Furthermore, it can easily build desktop apps for Windows, Linux, and macOS.

Animation Support

The intuitive, user-friendly API ensures easy development of high-end, complex animation timelines with minimum programming.

Code Generation

The framework is so smart that it can convert templates into well-versed code for modern JavaScript virtual machines.

Templates

It helps developers to develop UI views with an easy, simple yet powerful template syntax.

Question5: Tell the best benefits of Angular over other frameworks.

Answer:

Right off the Bat Features: Angular offers developers built-in features from RxJS library, routing, state management, to HTTP services right off the bat. This allows developers to not look further or separately for the necessary features.

Declarative UI: Angular framework is a declarative language thus it is easier than JavaScript when deploying HTML to provide the UI of an application.

Long-term Google Support: As developed by Google, the brand has big plans for the Angular framework to further scale up its ecosystem.

We believe that with the help of these Angular interview questions and answers, you can get the job of your dream as an Angular developer. These questions will boost your confidence. A bonus tip, if you don’t know a question, just simply say no then beat around the bush and add unnecessary details. Applicants that are honest and forthright are preferred over those who are know-it-all!
