Sure, here are some Angular interview questions:
What is Angular?
Angular is an open-source web application framework used for developing dynamic, single-page applications. It is written in TypeScript and is maintained by Google.
What are the advantages of using Angular?
Angular provides a range of benefits such as modular architecture, dependency injection, declarative templates, and Two-way data binding, improved performance, easy testing and debugging, and better scalability.
What is the difference between AngularJS and Angular?
AngularJS is the first version of Angular, while Angular is the newer and completely rewritten version. Angular uses TypeScript, while AngularJS uses JavaScript. Angular also uses a component-based architecture, while AngularJS uses a directive-based architecture.
What is a component in Angular?
A component is a basic building block of an Angular application that represents a part of the user interface. It includes the HTML template, CSS styles, and TypeScript code that define the logic and behavior of the component.
What is dependency injection in Angular?
Dependency injection is a design pattern in which the dependent objects are provided by an external framework rather than being created within the class itself. In Angular, it is used to inject services, components, and other dependencies into the application.
What is a service in Angular?
A service is a class that provides functionality to different parts of an Angular application. It is typically used to share data and logic across components, and can be injected into components, other services, or any other Angular class.
What is a directive in Angular?
A directive is a marker on a DOM element that tells Angular to attach a particular behavior or functionality to that element. It can be used to manipulate the DOM, add event listeners, and create reusable components.
What is lazy loading in Angular?
Lazy loading is a technique used in Angular to load modules only when they are needed. It helps to reduce the initial load time of the application and improve its performance.
These are just a few examples of Angular interview questions. Depending on the level of expertise required for the job, the interviewer may ask more advanced questions as well.
