Question

What is Angular and what are its key features?

Answer

Angular is a comprehensive, opinionated framework for building single-page applications (SPAs) using TypeScript, developed and maintained by Google. Unlike libraries (React, Vue), Angular is a full framework — it provides everything out of the box.

Key Features

• Component-based architecture — UIs are built from composable, reusable components
• TypeScript-first — strong typing, interfaces, decorators throughout
• Dependency Injection — built-in hierarchical DI system for sharing services
• Angular CLI — scaffolding, building, testing, linting from the command line
• Angular Router — feature-rich client-side routing with lazy loading and guards
• Reactive Forms & Template Forms — two complete approaches to form handling
• RxJS integration — Observables used throughout HttpClient, Router, Forms
• Angular CDK — accessible UI primitives (drag-drop, overlay, virtual scroll)
• Signals (Angular 16+) — fine-grained reactivity without Zone.js
