React has 45% market share among JavaScript frameworks. Angular has 17%. Both build excellent web applications. But they take fundamentally different approaches, and the right choice depends on your project.
The Fundamental Difference
React is a UI library. It renders components. Everything else — routing, state management, data fetching — comes from the ecosystem. You pick the tools.
Angular is a full framework. It includes routing, state management, forms, HTTP client, testing utilities, and build tools. Opinionated and comprehensive.
Think of it this way: React is a set of LEGO bricks. Angular is a pre-designed LEGO set with instructions.
Performance
Bundle Size
- React (core): 6.4 KB gzipped
- React DOM: 130 KB gzipped
- Typical React app: 200-400 KB total JavaScript
- Angular (core + common): ~130 KB gzipped
- Typical Angular app: 300-600 KB total JavaScript
React delivers smaller bundles by default because you only include what you use.
Runtime Performance
Both frameworks perform well for typical business applications. The differences are negligible for most use cases. React's virtual DOM and Angular's change detection both handle updates efficiently.
For high-performance requirements, React with Next.js supports server components that send zero JavaScript to the client for static content — something Angular is still developing with server-side rendering.
Core Web Vitals
In our experience building with both:
| Metric | React (Next.js) | Angular |
|---|---|---|
| LCP | 1.2-2.0s | 1.8-3.0s |
| FID | < 50ms | < 100ms |
| CLS | < 0.05 | < 0.1 |
| Lighthouse | 85-100 | 65-85 |
React with Next.js consistently achieves better Core Web Vitals due to server-side rendering, static generation, and automatic code splitting.
Developer Experience
Learning Curve
React: Gentle learning curve for basics. JSX is intuitive if you know HTML and JavaScript. However, the ecosystem decisions (which router? which state manager? which data fetching library?) require experience.
Angular: Steep learning curve. TypeScript required. Must learn Angular-specific concepts: modules, decorators, dependency injection, observables (RxJS), pipes, directives. Takes 3-6 months to become productive.
TypeScript Support
React: TypeScript is optional but widely adopted (~80% of new React projects use TypeScript). Integration is clean but some patterns require type gymnastics.
Angular: TypeScript is required. Angular's type support is deeply integrated and generally excellent. The framework was designed for TypeScript from the start.
Developer Ecosystem
React: 18 million weekly npm downloads. The largest ecosystem of any JavaScript framework. Thousands of component libraries, tools, and resources.
Angular: 3.5 million weekly downloads. Smaller but mature ecosystem. Google-backed tools and libraries. Excellent documentation.
For Business Websites Specifically
Marketing Sites and Landing Pages
Winner: React (Next.js)
Server-side rendering, static generation, and image optimization make Next.js ideal for marketing websites. Faster load times mean better SEO and higher conversion rates. The component model makes building reusable page sections efficient.
Angular can build marketing sites but lacks the Static Site Generation maturity of Next.js.
Web Applications (Dashboards, Portals, Admin)
Winner: Tie (slight Angular edge for enterprise)
Angular's comprehensive framework includes everything needed for complex applications: forms with validation, HTTP interceptors, guards, resolvers, and modular architecture. For large enterprise applications with 50+ developers, Angular's opinionated structure prevents architectural chaos.
React with established patterns (Next.js App Router, React Query, Zustand) achieves the same results with more flexibility but requires architectural discipline.
E-commerce
Winner: React (Next.js)
E-commerce demands performance. Shopify Hydrogen uses React. Vercel Commerce uses Next.js. The ecosystem for headless commerce is React-dominant.
Progressive Web Apps
Winner: Tie
Both frameworks support PWAs well. Angular has the @angular/pwa schematic. React has Workbox integration with Next.js PWA plugins.
Hiring and Talent
React developers are more abundant and generally less expensive. The supply-demand dynamic:
- React developers on LinkedIn: ~2.3 million
- Angular developers on LinkedIn: ~1.1 million
- Average React developer salary: $110K-150K
- Average Angular developer salary: $115K-160K
React talent is easier to find and slightly more affordable.
Our Recommendation
For business websites, marketing sites, and web applications, we recommend React with Next.js. Our reasoning:
- Better performance out of the box (SSR, SSG, ISR)
- Larger talent pool for scaling your team
- Dominant ecosystem for modern web development
- Faster development velocity for most project types
- Better SEO through server-side rendering
Angular remains an excellent choice for large enterprise applications with complex forms, strict architectural requirements, and teams that benefit from opinionated framework decisions.
