Each component consists of TypeScript class containing a decorator, an HTML template, and styles.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Template \u2013 Templates are in the form of HTML tags that are present in components. These template are used to declare how a component must be rendered.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Modules \u2013 Modules are also considered as building blocks in Angular. However, modules have a specific set of capabilities or workflow.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Services \u2013 Service could be broadly defined as a class with a well-defined purpose.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Metadata \u2013 Metadata is used to add data to a class.

It becomes capable of doing so by following modern principles of web designing, such as graceful degradation and browser probability.<\/span><\/p>\n<p style=\"text-align: center;\"><strong>Also read: <\/strong><a href=\"https:\/\/hbr.org\/2019\/11\/how-to-deflect-difficult-questions-in-an-interview-or-negotiation\" target=\"_blank\" rel=\"noopener\">How to Deflect Difficult Questions in an Interview or Negotiation<\/a><\/p>\n<h2><b>Angular interview questions for 2 years-experience<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Angular coding interview questions are perfect if you preparing for Angular interview questions for 2 years-experience.<\/span><\/p>\n<h3><strong>1.What are Pipes in Angular?\u00a0<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">Pipes are simple functions\u00a0designed to accept an input value, process, and return as an output, a transformed value in a more technical understanding. Angular supports several built-in pipes. However, you can also create custom pipes that cater to your needs.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Some key features include:\u00a0<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Pipes are defined using the pipe \u201c|\u201d symbol.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Pipes can be chained with other pipes.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Pipes can be provided with arguments by using the colon (:) sign.<\/span><\/li>\n<\/ul>\n<h3><strong>2.What is the PipeTransform interface?<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">As the name suggests, the interface receives an input value and transforms it into the desired format with a transform() method. It is typically used to implement custom pipes.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">import {Pipe, PipeTransform} from \u2018@angular\/core\u2019;<\/span><\/p>\n<p><span style=\"font-weight: 400;\">@Pipe({<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Name:demopipe\u2019<\/span><\/p>\n<p><span style=\"font-weight: 400;\">})<\/span><\/p>\n<p><span style=\"font-weight: 400;\">export class DemopipePipe implements PipeTransform{<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">transform (value: unknown, \u2026.args:unknown[]):unknown {<\/span><\/p>\n<p><span style=\"font-weight: 400;\">return null;<\/span><\/p>\n<p><span style=\"font-weight: 400;\">}<\/span><\/p>\n<p><span style=\"font-weight: 400;\">}<\/span><\/p>\n<h2><b>Angular interview questions for 3 years-experience<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Angular technical interview questions are to be expected for all developer roles. The top Angularjs interview questions and answers for 3 years-experience are \u2013<\/span><\/p>\n<h3><strong>1.What is the scope?<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">In Angular, a scope is an object that refers to the application model. It is a context in which expressions can be executed. These scopes are grouped hierarchically, comparable to the DOM structure of the application. A scope aids in the propagation of various events and the monitoring of expressions<\/span><\/p>\n<h3><strong>2.What are annotations in Angular ?<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">These are language features that are hard-coded. Annotations are merely metadata that is set on a class to reflect the metadata library. When a user annotates a class, the compiler adds an annotations property to the class, saves an annotation array in it, and then attempts to instantiate an object with the same name as the annotation, providing the metadata into the constructor. Annotations in AngularJs are not predefined, therefore we can name them ourselves.<\/span><\/p>\n<h2><b>Angular interview questions for 4 years-experience<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Angular developer interview questions may focus on a candidate&#8217;s experience with Angular, including their understanding of the framework&#8217;s architecture, ability to build and maintain components, directives, services, and Angular security interview questions.

This means they take lesser time to code and classes that you are testing should be more isolated. For example, a Login Feature normally has Validation and Authentication logic. They should be written in two separate classes like LoginValidator and LoginAuthenticator. Based on these two classes, you write test scripts.\u00a0<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">When you try to test Networking functions, like in LoginAuthenticator, you should use Mock Response to test for both positive and negative responses.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Integration Tests sits at the next level after Unit Tests. Here, you will use Real Network Responses, by hitting the real server endpoint, and test that the small units you have written are able to work together.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>UI<\/b> <b>Testing<\/b><span style=\"font-weight: 400;\"> automates repetitive tasks to ensure that your most critical UI interactions keep working as you\u2019re adding new features or refactoring your app\u2019s codebase.
