Angular Interview Questions and Answers - English
Here are some common Angular interview questions along with their answers: What is Angular? Angular is a TypeScript-based open-source web application framework developed and maintained by Google. It is used for building dynamic, single-page web applications (SPAs) and is popular for its features like data binding, dependency injection, and modular design. What are the key features of Angular? Key features of Angular include: Two-way data binding Dependency injection Directives Components Services Routing Forms HTTP client Modular architecture What is the difference between AngularJS and Angular? AngularJS (Angular 1.x) is an older version of the framework written in JavaScript, while Angular (Angular 2 and above) is a complete rewrite of AngularJS using TypeScript. Angular offers better performance, modularity, and tooling compared to AngularJS. Angular introduces features like components, modules, and improved dependency injection that were not present in AngularJS. What are components in Angular? Components are the building blocks of an Angular application. They are TypeScript classes with an associated HTML template and styles. Each component encapsulates a part of the user interface and behaviour of the application. What is Angular CLI? Angular CLI (Command Line Interface) is a command-line tool used for scaffolding, building, and managing Angular applications. It provides commands for generating components, services, modules, and other artifacts, as well as for running development servers and building production bundles. What is lazy loading in Angular? Lazy loading is a technique in Angular where modules are loaded asynchronously when needed, rather than loading all modules at once when the application starts. This improves application startup time and reduces initial bundle size. Explain Angular directives. Directives in Angular are markers on a DOM element that tell Angular's HTML compiler (part of the framework) to attach a specified behaviour to that DOM element or transform the DOM element and its children. Angular provides built-in directives like ngIf, ngFor, ngModel, etc., and allows developers to create custom directives as well. What is dependency injection in Angular? Dependency injection (DI) is a design pattern used in Angular to inject dependencies (services or objects) into components or other services. DI allows for better modularity, testability, and maintainability by decoupling components and their dependencies. Explain Angular routing. Angular routing is a mechanism for navigating between different components in an Angular application. It allows developers to define routes with corresponding components and templates, set up navigation paths, and handle navigation events. Angular's router also supports features like lazy loading, route guards, and parameterized routes. How do you handle HTTP requests in Angular? Angular provides an HTTP Client module for making HTTP requests to backend servers. Developers can use methods like get(), post(), put(), delete(), etc., provided by the HTTP Client service to perform CRUD operations and handle responses using Observables. These questions cover a range of topics commonly discussed in Angular interviews, from basic concepts to more advanced features and best practices.
