Explain
Angular allows developers to build modular, scalable, and maintainable web applications.
It uses TypeScript for strong typing and modern JavaScript features.
Angular employs a component-based architecture for reusable UI and logic.
Core Features
Modules for code organization
Services for business logic
Directives for dynamic DOM manipulation
Routing for SPA navigation
Reactive forms and template-driven forms
Basic Concepts Overview
Components and templates
Modules and NgModule
Services and dependency injection
Data binding: interpolation, property, event, two-way
Directives: structural and attribute
Project Structure
src/app/ - main application code
src/assets/ - static files
src/environments/ - environment configuration
angular.json - build configuration
package.json - dependencies and scripts
Building Workflow
Generate components, services, and modules with Angular CLI
Write HTML templates with Angular directives
Manage state and events with services or RxJS
Use Angular Router for navigation
Build production bundle with `ng build --prod`
Difficulty Use Cases
Beginner: simple component-driven apps
Intermediate: SPAs with routing and forms
Advanced: Reactive apps with RxJS
Expert: Large-scale enterprise applications
Community: contributing to Angular libraries or CLI
Comparisons
More structured than React or Vue for large apps
Stronger typing with TypeScript than plain JS frameworks
Enterprise-friendly with CLI and tooling
Larger bundle size than lightweight frameworks
Supports reactive programming better than jQuery
