  title: JavaScript Frameworks Comparison (React, Vue, Angular, Svelte)
  description: "Compare modern JS frameworks: React (component-based, virtual DOM), Vue (progressive, approachable), Angular (enterprise, TypeScript-first), Svelte (compiler-based, no runtime)."
  summary: A comparison of React, Vue, Angular and Svelte by type, paradigm, key features, strengths, weaknesses, learning curve, use cases and ecosystem notes.
  use_when:
    - You are choosing a front-end framework or explaining the differences.
    - You need the main trade-offs in one place.
  caveats:
    - Frameworks evolve quickly; versions, tooling and performance claims date quickly.
    - Team experience and existing code often matter more than technical differences.

  frameworks:
    - name: React
      type: Library
      paradigm: Component-based, Declarative
      key_features:
        - Virtual DOM for efficient updates
        - JSX syntax for templating
        - Unidirectional data flow
        - Hooks for state and side effects
        - Large ecosystem (React Router, Redux, Next.js)
      pros: High performance with virtual DOM, massive ecosystem, flexible architecture, strong community, excellent for SPAs and mobile (React Native).
      cons: Steep learning curve with JSX and hooks, frequent best-practice changes, requires build tooling, boilerplate for state management.
      learning_curve: Moderate to High
      use_case: Large-scale SPAs, complex UIs, mobile apps via React Native, SSR with Next.js.
      ecosystem_notes: Meta-maintained. Industry standard with extensive third-party libraries, tools, and job market dominance.
    - name: Vue
      type: Framework
      paradigm: Progressive, Component-based
      key_features:
        - Approachable with HTML-based templates
        - Reactive data binding
        - Composition API and Options API
        - Single-file components (.vue files)
        - Vue Router and Vuex/Pinia for state
      pros: Gentle learning curve, excellent documentation, flexible progressive adoption, good performance, balanced features.
      cons: Smaller ecosystem than React, enterprise adoption lower than Angular/React, ecosystem fragmentation between Options and Composition API.
      learning_curve: Low to Moderate
      use_case: Startups,中小型应用, gradual adoption in existing projects, rapid prototyping.
      ecosystem_notes: Community-driven ( Evan You ). Officially supported tools (Vue Router, Pinia, Vite integration). Growing in Asia and Europe.
    - name: Angular
      type: Framework
      paradigm: MVC / Component-based
      key_features:
        - TypeScript-first architecture
        - Two-way data binding
        - Dependency injection built-in
        - RxJS integration for reactive programming
        - Angular CLI for scaffolding and builds
        - Built-in HTTP client, forms, routing
      pros: Complete out-of-the-box solution, strong typing with TypeScript, excellent for large enterprise teams, long-term Google support, robust testing tools.
      cons: Steep learning curve, verbose boilerplate, larger bundle size, rigid structure, slower adoption of newer JS features.
      learning_curve: High
      use_case: Enterprise applications, large teams with structured processes, projects requiring strong typing and long-term maintainability.
      ecosystem_notes: Google-maintained. Enterprise-focused with strong tooling (Angular Material, NG-Zorro). Used heavily in finance, government, large orgs.
    - name: Svelte
      type: Compiler
      paradigm: Compiler-based, Declarative
      key_features:
        - Compiles to vanilla JS at build time (no runtime)
        - Truly reactive assignments (no useState)
        - Less boilerplate, smaller bundles
        - SvelteKit for full-stack apps (SSR, SSG)
        - Native CSS scoping per component
      pros: Excellent runtime performance, minimal bundle size, clean syntax, less boilerplate, great for performance-critical apps.
      cons: Smaller ecosystem and community, fewer third-party libraries, less industry adoption, newer and less proven at massive scale.
      learning_curve: Low to Moderate
      use_case: Performance-critical apps, small-to-medium projects, embedded widgets, teams prioritizing bundle size and simplicity.
      ecosystem_notes: Community-driven with Svelte Society. Growing rapidly but still niche compared to React/Vue/Angular. SvelteKit provides full-stack capabilities.
