Frequently Asked Questions (FAQs) on Angular:

1. What is Angular, and how is it different from AngularJS?

Angular is a platform and framework for building single-page client applications using HTML, CSS, and TypeScript. Angular is a complete rewrite of its predecessor, AngularJS. While AngularJS was based on the model-view-controller (MVC) design, Angular uses a component-based architecture.

2. How does Angular’s component-based architecture work?

Angular applications are composed of a set of nested components, each encapsulating its own view, data, and behavior. Components communicate with one another using inputs, outputs, and services, allowing for a modular and reusable structure.

3. What are directives in Angular?

Directives are classes that add additional behavior to elements in your Angular templates. They can change the structure of the DOM or modify its attributes. There are three types of directives: component directives, structural directives (like *ngIf and *ngFor), and attribute directives (like ngStyle and ngClass).

4. What’s the difference between template-driven and reactive forms?

Template-driven forms are driven by derivatives in the template itself, using ngModel. Reactive forms are more robust, scalable, and reusable, and they are defined in the component class using the FormBuilder, FormGroup, and FormControl classes.

5. How does Angular handle dependency injection?

Dependency Injection (DI) is a core feature of Angular, allowing a class to request dependencies from external sources rather than creating them. Angular’s DI provides instances of services or values that a class needs to perform its function.

6. What are Observables in Angular?

Observables, coming from the RxJS library, are used in Angular to handle asynchronous operations and events. They provide a way to handle streams of data over time, allowing for complex operations like map, filter, and merge to be performed.

7. How does Angular’s change detection mechanism work?

Angular checks for changes in the data properties and updates the DOM to reflect those changes. It uses a zone.js library to intercept asynchronous operations, then runs change detection to check the old and the new values. Developers can optimize this process by using strategies like OnPush.

8. What’s the purpose of Angular’s NgModules?

NgModules consolidate components, directives, and pipes into cohesive blocks of functionality. They provide a compilation context for templates and can also play a role in application runtime configuration.

9. How can you optimize the performance of an Angular application?

There are various strategies: implementing lazy loading for modules, using the OnPush change detection strategy, optimizing the build using Ahead-of-Time (AOT) compilation, minimizing the number of HTTP requests, and using trackBy with *ngFor are some popular techniques.

10. What is the Angular CLI, and what can it do?

Angular CLI is a command-line interface tool that helps automate the development workflow. It can be used to create a new Angular application, generate components, services, modules, and perform tasks like testing, building, and deploying the application.

These varied question types ensure that you have a well-rounded grasp of both the theoretical and practical aspects of Angular development.
