| content.faq | `[{"answer":"React is a JavaScript library for building user interfaces using a component-based architecture. It uses a declarative programming model, allowing developers to describe what the UI should look like for any given application state. React employs a virtual DOM abstraction to efficiently update only the parts of the interface that have changed.","source":"https://github.com/facebook/react","question":"What is React?","confidence":0.95},{"answer":"Yes, React is open source software released under the MIT license, permitting free use, modification, and distribution in both commercial and personal projects. There are no licensing fees or cost barriers to using React.","source":"https://github.com/facebook/react","question":"Is React open source and free to use?","confidence":0.95},{"answer":"React is maintained by Meta (formerly Facebook) along with contributions from the open-source community. Meta created React to solve its own internal UI challenges and later open-sourced it to enable broader adoption and community feedback.","source":"https://github.com/facebook/react","question":"Who maintains React?","confidence":0.94},{"answer":"React is built on JavaScript and TypeScript, running natively in web browsers. Meta also maintains React Native, a separate framework that allows developers to apply React principles to build native iOS and Android mobile applications using JavaScript.","source":"https://github.com/facebook/react","question":"What programming languages and platforms does React support?","confidence":0.95},{"answer":"Popular alternatives include Vue.js (a progressive JavaScript framework), Angular (a comprehensive full-featured framework), Svelte (a compiler-based framework), and Preact (a lightweight React-compatible library). Each offers different trade-offs in learning curve, ecosystem size, and performance characteristics.","source":"https://github.com/facebook/react","question":"What are the main alternatives to React?","confidence":0.93},{"answer":"React applications can use multiple rendering strategies: client-side rendering (browser handles all rendering), server-side rendering (server generates initial HTML via Node.js), or static site generation (pre-built HTML files). Deployments typically run on web servers, content delivery networks, or serverless computing platforms.","source":"https://github.com/facebook/react","question":"How are React applications typically deployed?","confidence":0.94},{"answer":"React projects typically use build tools such as Webpack, Vite, or Parcel for bundling and development. Common complementary libraries include React Router for navigation, Redux or Context API for state management, and Jest or React Testing Library for testing.","source":"https://github.com/facebook/react","question":"What build tools and libraries are commonly paired with React?","confidence":0.93}]` | `[{"answer":"SolidJS is a JavaScript library for building user interfaces using a declarative programming model with JSX. Unlike frameworks that use a virtual DOM, SolidJS compiles templates directly into real DOM nodes and updates them through fine-grained reactivity, where only code dependent on changed state will re-execute. This approach results in smaller bundle sizes and optimal runtime performance.","source":"https://github.com/solidjs/solid","question":"What is SolidJS and how does it work?","confidence":0.95},{"answer":"SolidJS uses fine-grained reactivity and direct DOM compilation instead of React's virtual DOM reconciliation. In SolidJS, components are functions that run once, and only the specific reactive values that change trigger updates, whereas React re-renders components when state changes. This typically results in better performance and smaller compiled bundle sizes compared to React applications.","source":"https://github.com/solidjs/solid","question":"How does SolidJS differ from React?","confidence":0.9},{"answer":"Yes, SolidJS is completely open-source and free to use under the MIT license. The MIT license permits both commercial and personal use, modification, and distribution without cost or licensing restrictions.","source":"https://github.com/solidjs/solid","question":"Is SolidJS open-source and what license does it use?","confidence":0.95},{"answer":"Yes, SolidJS has first-class TypeScript support and is built on JSX and TypeScript. To use TypeScript with SolidJS, you configure your tsconfig.json with jsx set to 'preserve' and jsxImportSource set to 'solid-js'. This provides full type safety for components, props, and reactive state.","source":"https://github.com/solidjs/solid","question":"Does SolidJS support TypeScript?","confidence":0.9},{"answer":"Fine-grained reactivity refers to a system where the framework tracks which pieces of code depend on which data, and only re-executes the code that depends on changed values. In SolidJS, when state changes, only the specific DOM updates and side effects that depend on that state will run, rather than re-rendering entire components. This precision minimizes unnecessary computation and DOM manipulation.","source":"https://github.com/solidjs/solid","question":"What does 'fine-grained reactivity' mean in SolidJS?","confidence":0.95},{"answer":"SolidJS is suitable for building interactive web applications, single-page applications (SPAs), and progressive web apps. It supports server-side rendering with progressive hydration, error boundaries, suspense for async operations, and context-based state management. The framework also enables authoring custom web components for reusable UI elements.","source":"https://github.com/solidjs/solid","question":"What can I build with SolidJS?","confidence":0.9},{"answer":"SolidJS integrates with modern build tools like Vite and includes ecosystem libraries for state management (built-in Stores and Context), component libraries like Kobalte, and community packages like solid-primitives. The framework also works well with standard JavaScript libraries that directly manipulate the DOM, such as D3 for data visualization.","source":"https://github.com/solidjs/solid","question":"What build tools and ecosystem does SolidJS have?","confidence":0.85},{"answer":"No, SolidJS does not use a virtual DOM. Instead, it compiles JSX templates directly into real DOM nodes at build time. This direct compilation approach eliminates the overhead of virtual DOM diffing and contributes to SolidJS's performance advantages and smaller bundle size.","source":"https://github.com/solidjs/solid","question":"Does SolidJS use a virtual DOM?","confidence":0.95}]` |
| description.long | A library that enables developers to construct user interfaces using individual components as building blocks. React components are JavaScript functions that receive data and render the appropriate output, supporting both web applications and native mobile development through frameworks. | A JavaScript library for constructing user interfaces using fine-grained reactivity, updating only what changes rather than diffing virtual DOMs. Emphasizes performance through reactive primitives and supports modern patterns like async handling, server-side rendering, hydration, and streaming. |
