6. How do you Implement Forms in Angular?

Answer: Angular offers template-driven and reactive forms. For template-driven forms, use ngModel for two-way data binding. For reactive forms, create controls and handle validation programmatically.

Template-driven form:

htmlCopy code
<input type="text" [(ngModel)]="name" required>

Reactive form:

typescriptCopy code
this.form = new FormGroup({
name: new FormControl('', Validators.required),

7. Explain the Role of Directives in Angular.

Answer: Directives are instructions in the DOM, triggered by Angular. Structural directives like ngIf manipulate the structure, while attribute directives like ngStyle modify the appearance of elements.

htmlCopy code
<!-- Structural directive -->
<div *ngIf="loggedIn">Welcome, User!</div>

<!-- Attribute directive -->
<p [ngStyle]="{ color: 'blue', 'font-size': '18px' }">Styled Text</p>

8. What is Angular CLI? How do you Create a New Project?

Answer: Angular CLI is a command-line tool to scaffold, develop, and deploy Angular applications. Create a new project using the command:

bashCopy code
ng new project-name

9. How can you Pass Data between Components in Angular?

Answer: Data can be passed from parent to child using input properties (@Input) and from child to parent using output properties (@Output) with event emitters.

Parent component:

typescriptCopy code
<app-child [data]="parentData"></app-child>

Child component:

typescriptCopy code
@Input() data: any;

10. Explain Angular Modules and their Types.

  • Root Module: The main module that bootstraps the application.
  • Feature Module: Contains features and is imported when needed.
  • Shared Module: Holds components, directives, and pipes shared across modules.
