Introduction to Angular

1. What is Angular?

Angular is a popular open-source web application framework developed and maintained by Google. It is a comprehensive front-end framework that simplifies the development of dynamic, single-page web applications (SPAs) and supports the MVC (Model-View-Controller) architecture.

• Angular is often confused with AngularJS; however, Angular is a complete rewrite and is referred to as “Angular” without the “JS.”
• It is written in TypeScript, a superset of JavaScript, which brings strong typing and other features to enhance code quality.

Key Features and Advantages

Angular comes with a plethora of features that make it a powerful choice for modern web development.

Two-way Data Binding: Angular facilitates automatic synchronization between the model and the view, reducing the need for boilerplate code.

// Example of two-way binding in Angular
<input [(ngModel)]="user.name" />

Modular Architecture: Applications are built using modules, making code organization and maintenance more manageable.

// Example of an Angular module
@NgModule({
  declarations: [AppComponent],
  imports: [BrowserModule],
  bootstrap: [AppComponent]
})
export class AppModule { }

Dependency Injection: Angular has a built-in dependency injection system that makes it easy to manage and test components.

// Example of dependency injection in Angular
constructor(private userService: UserService) { }

Reusable Components: Components are the building blocks of an Angular application, promoting reusability and maintainability.

// Example of an Angular component
@Component({
  selector: 'app-user',
  templateUrl: './user.component.html',
  styleUrls: ['./user.component.css']
})
export class UserComponent { }

Angular CLI (Command Line Interface): The CLI streamlines the development process by providing commands for tasks like scaffolding, building, and testing.

# Example of creating a new Angular component using CLI
ng generate component user
