What is Angular?
Angular is a platform and framework for building single-page client applications using HTML and TypeScript. It's a complete rewrite of AngularJS and provides a comprehensive solution for building large-scale applications.
Developed by Google, Angular is used by companies like Microsoft, IBM, and many Fortune 500 companies for building enterprise applications. It provides a complete framework with everything you need for large-scale development.
Key Features
TypeScript First
Built with TypeScript for better development experience and type safety.
Example: interface User { id: number; name: string; email: string; }
Dependency Injection
Built-in dependency injection system for better testability and modularity.
Example: constructor(private userService: UserService) { }
Component Architecture
Component-based architecture with lifecycle hooks and data binding.
Example: @Component({ selector: 'app-user', templateUrl: './user.component.html' })
RxJS Integration
Reactive programming with observables for handling async operations.
Example: this.userService.getUsers().subscribe(users => this.users = users)
Angular CLI
Command-line interface for project generation and development tasks.
Example: ng new my-app, ng generate component user, ng serve
Forms & Validation
Powerful form handling with built-in validation and custom validators.
Example: Reactive forms, template-driven forms, custom validators
