What Is React Native? The Complete 2026 Guide to Cross-Platform Mobile Development

Building mobile apps used to mean choosing: write everything twice for iOS and Android, or settle for slow, clunky hybrid apps that disappointed users. Then Facebook changed the game. In 2015, they released React Native and proved you could write code once in JavaScript and ship truly native apps to millions of devices. Ten years later, that promise isn't just real—it's powering apps you use every day. Instagram handles 2 billion users with it. Tesla owners control their cars with it. Shopify merchants run billion-dollar stores from it. If you've wondered whether one codebase can really compete with native apps, the answer is staring at you from your phone screen right now.

Whatever you do — AI can make it smarter. Begin Here

TL;DR

• React Native lets you build real native mobile apps using JavaScript and React, sharing up to 95% of code between iOS and Android

• Created by Meta (Facebook) in 2015, it powers apps used by billions including Instagram, Shopify, Tesla, Discord, and Microsoft products

• As of 2025, React Native reaches 4 million weekly downloads (doubled from 2024) and powers over 11 million websites globally (Callstack, 2025)

• The New Architecture (Fabric, JSI, TurboModules) delivers near-native performance with 40% faster cold starts via Hermes engine (Nucamp, 2025)

• Companies save 30-40% in development costs compared to separate native teams while maintaining 99.9% crash-free sessions (Shopify Engineering, 2025)

• React Native now supports iOS, Android, Windows, macOS, and web from a single codebase with Microsoft's backing

React Native is an open-source framework created by Meta that lets developers build mobile applications for iOS and Android using JavaScript and React. Instead of writing separate native code, developers write once in JavaScript, and React Native translates it into truly native components that look, feel, and perform like apps built with Swift or Kotlin. It powers major apps from Instagram to Tesla.

What React Native Actually Is

React Native is a cross-platform mobile application framework developed by Meta (formerly Facebook) that enables developers to build native mobile apps using JavaScript and React. Released as open source in March 2015, it fundamentally changed mobile development by allowing a single codebase to generate truly native user interfaces on both iOS and Android (Wikipedia, 2025).

The "native" part matters. React Native doesn't wrap your app in a web view like older hybrid frameworks (Cordova, PhoneGap). Instead, it translates your JavaScript components into actual native UI widgets. When you write a <View> in React Native, iOS renders a UIView and Android renders a ViewGroup. The user sees and interacts with real native components, not HTML pretending to be buttons.

According to ESpark Info's 2025 React statistics, React Native currently powers over 11 million websites worldwide, with React running on 4.8% of global websites. Professional developers show a 9% preference for React Native in cross-platform solutions, while the broader React ecosystem accounts for 41.6% of professional developer usage (Stack Overflow, 2024).

The framework follows React's component-based architecture, meaning developers build UIs from reusable, self-contained pieces. If you know React from web development, most concepts transfer directly. You write JSX, manage state with hooks, and think in components. The difference is that instead of targeting the browser DOM, you're rendering to native mobile UI.

Key characteristics:

• Write once, run on multiple platforms – One JavaScript codebase generates native apps for iOS, Android, and increasingly Windows, macOS, and web

• Truly native components – Not web views; actual platform-native UI elements

• Live updates – Push JavaScript bundle updates without app store approvals for many changes

• Strong typing support – Full TypeScript integration for safer, more maintainable code

• Large ecosystem – Over 207,000+ stars on GitHub and 22 million weekly npm downloads (ESpark Info, 2025)

The Origin Story: Why Facebook Built It

In 2012, Facebook CEO Mark Zuckerberg made a public confession: "The biggest mistake we made as a company was betting too much on HTML5 as opposed to native." Facebook's mobile web app was slow, unstable, and frustrating for users. The company needed native apps but faced a brutal reality—building the same features twice (once in Objective-C for iOS, once in Java for Android) was draining engineering resources and slowing product velocity (Wikipedia, 2025).

Inside Facebook, engineer Jordan Walke started experimenting in 2013. He built a prototype that could generate iOS UI elements from a background JavaScript thread. The idea was radical: use JavaScript for business logic and React's declarative component model, but render to truly native widgets instead of web views (TechAhead, 2023).

Facebook held an internal hackathon in 2013 where Walke and his team proved the concept worked. By 2014, they had a small team building what would become React Native. The first production test came with Facebook Ads Manager for iOS, launched in February 2015 (Meta Engineering, 2016). Engineers who weren't familiar with React built a full iOS app with native look and feel in just five months.

The results stunned Facebook's leadership. The same team then built the Android version in three additional months, reusing most of the iOS codebase (Meta Engineering, 2015). Facebook announced React Native publicly at React.js Conf in January 2015. Engineer Tom Occhino told the audience: "What if we take the exact same React JavaScript we've been running on Web, and we can use it to power truly native applications?" (ADT Mag, 2015). The room erupted in applause.

Facebook open-sourced React Native for iOS on March 25, 2015, and for Android on September 14, 2015 (RisingStack, 2024). The philosophy was clear: they weren't chasing "write once, run anywhere" like failed hybrid frameworks. Instead, React Native promised "learn once, write anywhere"—use React principles everywhere, but customize for each platform when needed (ADT Mag, 2015).

Ten years later, that bet paid off. In October 2025, Meta donated React, React Native, and JSX to a new React Foundation under the Linux Foundation, cementing its role as critical open-source infrastructure (Wikipedia, 2025).

How React Native Works Under the Hood

React Native's architecture creates a bridge between JavaScript code and native platform APIs. Understanding this system helps explain both its capabilities and limitations.

The Three-Thread Model

A React Native app runs on three main threads:

1. JavaScript Thread – Executes your app logic, React components, and business code. Runs in a JavaScript engine (now Hermes by default since 2025)

2. Native/UI Thread – Handles native platform rendering, user input events, and native module operations

3. Shadow Thread – Calculates layout using Yoga (Facebook's implementation of Flexbox) before committing changes to the UI thread

Your JavaScript code never directly manipulates native UI. Instead, it sends instructions over a bridge, and the native side interprets and executes them.

The Original Bridge Architecture (Pre-2025)

In the original architecture (React Native versions before 0.70), JavaScript and native code communicated via an asynchronous bridge. Every interaction required serializing data to JSON, sending it across the bridge thread, and deserializing it on the other side (Medium, 2025).

This worked but created bottlenecks:

• JSON serialization overhead slowed high-frequency updates

• Asynchronous nature caused delays in UI responsiveness

• Large data transfers (like camera frames or complex graphics) struggled with serialization costs

  
  

Components and Rendering

When you write a component in React Native:

<View style={styles.container}>
  <Text>Hello World</Text>
  <Button onPress={handlePress} title="Click Me" />
</View>

React Native's renderer:

1. Creates a virtual representation (React's Virtual DOM equivalent)

2. Calculates layout with Yoga on the Shadow thread

3. Sends native commands over the bridge

4. Native modules render actual UIView/ViewGroup, UILabel/TextView, and UIButton/Button widgets

The user interacts with 100% native components. No web views are involved.

Styling

React Native uses a CSS-like JavaScript styling system that translates to native layout properties:

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#F5FCFF',
  }
});

Flexbox powers the layout engine (via Yoga), but instead of CSS strings, you use JavaScript objects. Units are density-independent pixels by default.

The New Architecture Revolution

In 2025, React Native's architecture underwent its most significant transformation since launch. The New Architecture replaces the async bridge with a modern, high-performance C++ core, eliminating many legacy bottlenecks (Callstack, 2025).

The Four Pillars

1. JSI (JavaScript Interface)

JSI replaces the old bridge with a lightweight C++ layer that enables direct, synchronous communication between JavaScript and native code (Medium, 2025). Instead of JSON serialization, JSI uses memory references.

Key benefits:

• Synchronous method calls when needed (no forced async delays)

• Zero serialization overhead for many operations

• Direct access to C++ objects from JavaScript

• Dramatically faster for high-frequency operations like camera frame processing

Example: VisionCamera, a popular camera library, processes ~30 MB frame buffers at 60 FPS—roughly 2 GB/second of data. The old bridge would choke; JSI handles it easily (React Native Docs, 2025).

2. Fabric (New Rendering System)

Fabric is the new UI renderer that replaces the old UI Manager. Built in C++, it provides:

• Synchronous layout measurements – Measure component sizes before paint, eliminating layout flicker

• Concurrent rendering support – Compatible with React 18's concurrent features

• Platform-agnostic core – Unified rendering logic across iOS, Android, and future platforms

• Improved type safety – Better compile-time checking reduces runtime crashes

Shopify reports that Fabric enabled "measure before paint" optimizations, leading to smoother and faster screen loads in their apps with hundreds of screens (Shopify Engineering, 2025).

3. TurboModules

TurboModules modernize how native modules load and execute:

• Lazy loading – Modules initialize only when first used, reducing startup time

• Direct JSI integration – Faster method invocation without bridge overhead

• Strong typing – TypeScript/Flow definitions generate type-safe native bindings via Codegen

• Improved performance – Synchronous calls when appropriate, async when needed

Traditional native modules loaded eagerly at app startup. TurboModules load on-demand, cutting cold start times significantly (GlobalDev, 2025).

4. Codegen

Codegen automatically generates C++, Java, Kotlin, and Objective-C bindings from TypeScript or Flow type definitions. This ensures:

• Type safety across the JavaScript-native boundary

• Reduced boilerplate code for native modules

• Compile-time error detection instead of runtime failures

  
  

Hermes: The Default Engine

As of 2025, Hermes is the default JavaScript engine for React Native on all platforms (React Native Development Company, 2025). Meta built Hermes specifically for mobile, optimizing for:

• Faster cold starts – Up to 40% faster app launch times

• Smaller bundle sizes – Bytecode compilation reduces file size

• Better memory efficiency – 20-30% less memory usage compared to JavaScriptCore

• Improved garbage collection – Fewer frame drops during GC pauses

According to Nucamp (2025), Hermes delivers approximately 40% faster cold starts and reduces memory consumption by 20-30% compared to the previous JavaScriptCore engine.

Performance Impact

The New Architecture became the default (and only) architecture in React Native 0.76, released in late 2025 (Callstack, 2025). Companies migrating report:

• Shopify: Achieved sub-500ms P75 screen load times in production apps serving millions of users (Shopify Engineering, 2025)

• General improvements: Faster animations, reduced jank, smoother scrolling, and better developer experience

Shopify successfully migrated their flagship Shopify Mobile and Point of Sale apps—hundreds of screens, extensive native modules, millions of merchants—while maintaining weekly releases and 99.9% crash-free sessions (Shopify Engineering, 2025).

React Native vs Native vs Other Frameworks

How does React Native stack up against alternatives?

React Native vs Native Development

Native Development means writing separate apps:

• iOS: Swift or Objective-C with UIKit or SwiftUI

• Android: Kotlin or Java with Jetty or Compose

Advantages of Native:

• Absolute best performance (no abstraction layer)

• Immediate access to all platform APIs

• Platform-specific UI paradigms feel perfectly natural

• No framework maintenance burden

Advantages of React Native:

• Single codebase (30-40% cost reduction, Nucamp 2025)

• Faster iteration with hot reload

• Shared business logic, API clients, state management

• JavaScript ecosystem and tooling

• Code reusability across mobile and web (with React Native Web)

When to choose native: Performance-critical apps (gaming, AR/VR, complex media processing), apps requiring cutting-edge platform features, or teams already expert in native development.

When to choose React Native: Most business apps, e-commerce, social apps, content platforms, internal tools, and MVPs where speed to market matters.

React Native vs Flutter

Flutter (Google, 2017) is React Native's main competitor.

	React Native	Flutter
Language	JavaScript/TypeScript	Dart
Rendering	Native components	Custom canvas (Skia)
UI Feel	Platform-native by default	Custom, requires tuning
Ecosystem	Massive (npm, React)	Growing, smaller
Developer Pool	62.3% of devs know JavaScript (ZenRows, 2025)	Smaller Dart community
Performance	Near-native with New Architecture	Excellent (compiled to native)
Backing	Meta, Microsoft, Expo, community	Google
Desktop Support	Windows, macOS (via Microsoft)	Windows, macOS, Linux

Flutter advantages: Faster rendering for animations, more consistent UI across platforms, growing rapidly.

React Native advantages: Larger ecosystem, JavaScript familiarity, better community library selection, stronger corporate backing from multiple companies.

According to recent surveys, 94% of companies using cross-platform frameworks choose React Native over alternatives like Flutter or Ionic, and it powers over half of global cross-platform apps (Nucamp, 2025).

React Native vs Xamarin, Cordova, Ionic

• Xamarin (Microsoft, C#): Older cross-platform solution. React Native has surpassed it in popularity and community activity.

• Cordova/PhoneGap: Hybrid web view wrappers. Much slower than React Native; largely obsolete for new projects.

• Ionic: Modern web-based hybrid framework with Capacitor. Fast development but still web views, not truly native UI.

React Native's combination of native performance, JavaScript ecosystem, and major corporate backing gives it a unique position.

Major Advantages

1. Code Reusability (60-95%)

Share most code between iOS and Android. Shopify achieved 95% code sharing in background systems (Shopify Engineering, 2025). Typical apps share 60-80% of code, with platform-specific customization where needed.

2. Faster Development (40-60% time savings)

React's component architecture with hot reload enables rapid iteration. Developers can see changes instantly without recompiling. ESpark Info (2025) reports 60% faster development times with React Native's component architecture compared to monolith approaches.

3. Cost Savings (30-40%)

One team instead of two. Nucamp (2025) and various cross-platform ROI studies show 30-40% cost reduction compared to maintaining separate native teams.

4. JavaScript Ecosystem

Access npm's 2+ million packages. Use popular libraries for state management (Redux, MobX, Zustand), navigation (React Navigation), animation (Reanimated), networking (Axios), testing (Jest), and more.

5. Over-the-Air Updates

Push JavaScript bundle updates directly to users without app store review for many changes. Fix bugs and add features faster. (Note: native code changes still require store updates.)

6. Strong Community

• 207,000+ GitHub stars (ESpark Info, 2025)

• 22 million weekly npm downloads (ESpark Info, 2025)

• 4 million weekly React Native downloads, doubled from 2024 (State of React Native, 2026)

• Active React Foundation stewardship under Linux Foundation (Wikipedia, 2025)

• Thousands of third-party libraries and components

  
  

7. Web Alignment

React Native code can run on web with React Native Web (used by Twitter's web app). Share business logic across mobile and web seamlessly.

8. Desktop Expansion

Microsoft-backed React Native for Windows and macOS enables desktop app development with the same codebase. Apps like Microsoft Office features use this capability (Callstack, 2025).

9. Developer Experience

• Hot/fast refresh for instant updates

• Chrome DevTools and React DevTools integration

• Excellent TypeScript support

• Familiar React patterns for web developers

• Growing AI-assisted tooling

Limitations and Challenges

1. Performance Ceiling

While near-native, React Native has a performance ceiling below pure native code. Complex 3D graphics, computationally intensive tasks, or apps requiring 120fps animations may struggle. However, the New Architecture with Hermes dramatically narrows this gap.

2. Large App Size

React Native apps are larger than equivalent native apps due to JavaScript runtime and framework overhead. Typical React Native apps add 20-30 MB compared to pure native implementations.

3. Native Module Learning Curve

Eventually, most apps need custom native modules for platform-specific features. Developers must learn Swift/Objective-C for iOS and Kotlin/Java for Android.

4. Third-Party Library Maintenance

Some community libraries lag behind React Native updates or become unmaintained. Critical dependencies need careful evaluation.

5. Initial Setup Complexity

React Native setup involves multiple tools: Node.js, CocoaPods, Android Studio, Xcode. Expo reduces this significantly, but bare React Native CLI has a steeper learning curve than native development.

6. Platform-Specific Bugs

Differences between iOS and Android behaviors sometimes require platform-specific code and testing.

7. New Architecture Migration

Apps built on old architecture face migration work to adopt the New Architecture. While Shopify succeeded, it required coordinated effort and testing.

When to Choose React Native

React Native is excellent for:

✅ Business apps (CRM, productivity, internal tools)

✅ E-commerce and marketplace apps

✅ Social media and content platforms

✅ Messaging and communication apps

✅ News and media apps

✅ On-demand service apps (delivery, transportation)

✅ Fintech and banking apps (non-trading interfaces)

✅ Healthcare patient portals

✅ IoT device control apps

✅ MVPs and rapid prototyping

Consider native development for:

⚠️ High-performance gaming

⚠️ Complex AR/VR experiences

⚠️ Apps requiring cutting-edge platform features immediately

⚠️ Real-time trading platforms with microsecond latency needs

⚠️ Apps with heavy computational processing (video editing, 3D rendering)

Decision framework:

1. Does your team know JavaScript? → Strong React Native signal

2. Need iOS and Android quickly? → React Native saves time

3. Limited budget? → 30-40% cost savings matter

4. Standard business app features? → React Native handles these well

5. Gaming or heavy graphics? → Native or Unity/Unreal better

6. Need web version too? → React Native Web enables code sharing

Getting Started: Setup and Tools

Option 1: Expo (Recommended for Beginners)

Expo is a managed workflow that simplifies React Native development. It handles native configuration, provides development tools, and enables building without Xcode/Android Studio locally.

Setup:

npm install -g expo-cli
expo init MyApp
cd MyApp
expo start

Scan QR code with Expo Go app on your phone to see live preview.

Expo advantages:

• No Xcode or Android Studio required initially

• Over-the-air updates built-in

• Simpler build and deployment

• Extensive SDK with pre-built modules (camera, maps, sensors)

• Expo Application Services (EAS) for cloud builds

Limitations:

• Some native modules require "ejecting" to bare workflow

• Slightly larger app size

  
  

Option 2: React Native CLI (Bare Workflow)

Full control over native code from the start.

Requirements:

• Node.js 18+

• iOS: macOS with Xcode 14+

• Android: Android Studio with SDK 33+

Setup:

npx react-native init MyApp
cd MyApp
npx react-native run-ios     # for iOS
npx react-native run-android # for Android

Key Tools:

• React Native DevTools: Integrated debugging, network inspection, profiling (2025 release)

• Flipper: Desktop debugging platform with plugins

• Reactotron: Development tool for React Native debugging

• React Navigation: Standard navigation library

• Reanimated: High-performance animations

• Hermes: Default JavaScript engine (enabled automatically)

  
  

Version Targeting (2026)

Always target the latest stable release. As of early 2026, that means React Native 0.80+. The New Architecture is enabled by default in 0.76+ (React Native Development Company, 2025).

Performance Deep Dive

Startup Time

Cold start speed matters. Hermes reduces React Native cold start time by ~40% compared to JavaScriptCore (Nucamp, 2025). Techniques to optimize further:

• Lazy load modules and screens

• Minimize initial bundle size

• Use inline requires

• Optimize native module initialization

Shopify achieved sub-500ms P75 screen load times in production (Shopify Engineering, 2025).

Frame Rate and Animations

Target: 60 FPS (16.67ms per frame) on most devices, 120 FPS on Pro devices.

Best practices:

• Use Reanimated for animations (runs on UI thread, not JS thread)

• Avoid expensive operations in render methods

• Use React.memo, useMemo, useCallback appropriately

• Leverage Fabric's synchronous layout for smooth updates

  
  

Memory Management

React Native memory usage improved 20-30% with Hermes (Nucamp, 2025). Monitor with:

• React DevTools Profiler

• Native platform profilers (Xcode Instruments, Android Profiler)

• Flipper memory plugins

Avoid memory leaks by properly cleaning up listeners, timers, and subscriptions in useEffect cleanup functions.

Bundle Size

JavaScript bundle size affects download and startup time:

• Code splitting with dynamic imports

• Remove unused dependencies

• Enable Hermes bytecode compilation

• Use ProGuard/R8 (Android) for native code shrinking

  
  

Network Performance

Use efficient data loading patterns:

• GraphQL for flexible data fetching (Relay, Apollo)

• REST with proper caching (React Query, SWR)

• Lazy loading and pagination

• Optimize images (WebP format, responsive loading)

The Ecosystem and Community

Community Size

• JavaScript developers worldwide: 62.3% of all developers use JavaScript (Stack Overflow, 2024, via ZenRows 2025)

2. Desktop-First Applications: Microsoft's continued investment in React Native Windows and macOS signals growing desktop adoption. Companies want unified codebases across mobile and desktop (Callstack, 2025).

3. WebAssembly Integration: While primarily for React web, WebAssembly patterns may influence React Native for compute-intensive tasks (Netguru, 2025).

4. Improved DevTools: React Native DevTools launched in 2025 with component tree inspection, network monitoring, and profiling—bringing web-style debugging to mobile (Galaxies.dev, 2025).

5. Monorepo Standardization: Tools like Nx and Turborepo enable managing React Native alongside web apps in unified codebases (GlobalDev, 2025).

Market Outlook

The cross-platform development market is expected to reach $546.7 billion by 2033 (Persistence Market Research, via TMS Outsource 2025). React Native is positioned as the second most recommended cross-platform framework with over 13% market share (TMS Outsource, 2025).

According to the 2024-2033 forecast, the React Native market specifically is expected to grow at a 16.7% CAGR (ESpark Info, 2025).

Stability and Maturity

Infinite Red team summarized it well: "React Native has moved past the experimental phase and into a polishing era, where the focus is on predictability, stability, and performance rather than reinventing core ideas" (Nucamp, 2025).

With the New Architecture stable, React Native 1.0 approaching, and backing from Meta, Microsoft, and the React Foundation, the framework's future looks secure.

Frequently Asked Questions

Q: Is React Native still relevant in 2026?

A: Absolutely. React Native reaches 4 million weekly downloads (doubled from 2024) and powers apps used by billions including Instagram, Shopify, and Tesla. The New Architecture and Hermes engine deliver near-native performance, and major companies continue investing heavily in the ecosystem.

Q: What's the difference between React and React Native?

A: React is a JavaScript library for building web user interfaces that run in browsers. React Native is a framework for building native mobile apps (iOS, Android) using React principles. Both use components and JSX, but React Native renders to native UI widgets instead of HTML DOM.

Q: Can React Native apps access device hardware like camera and GPS?

A: Yes. React Native provides APIs for camera, GPS, accelerometer, contacts, file storage, and more. For features not in the core framework, thousands of community libraries or custom native modules enable access to any platform capability.

Q: Do I need to know Swift or Kotlin to use React Native?

A: Not initially. You can build complete apps with only JavaScript/TypeScript knowledge. Eventually, for custom native modules or advanced platform-specific features, learning native code helps but isn't required for most developers.

Q: How does React Native performance compare to native apps?

A: With the New Architecture (Fabric, JSI, TurboModules) and Hermes engine, React Native delivers near-native performance for most use cases. Companies like Shopify achieve 99.9% crash-free sessions and sub-500ms screen loads. Performance-critical apps (gaming, heavy graphics) may still prefer pure native.

Q: Can React Native apps run on web?

A: Yes, via React Native Web. Companies like Twitter use React Native Web to share code between mobile apps and web. Results vary—it works well for some apps but isn't a perfect web solution for all use cases.

Q: What's Expo and do I need it?

A: Expo is a managed workflow and toolset that simplifies React Native development. It's not required but highly recommended for beginners. Expo handles native configuration, provides development tools, and offers cloud build services. You can always "eject" to bare React Native CLI if needed.

Q: How large are React Native apps?

A: Typical React Native apps are 20-30 MB larger than equivalent native apps due to JavaScript runtime and framework overhead. Optimization techniques can reduce this. The tradeoff is faster development and code sharing.

Q: Can existing native apps integrate React Native?

A: Yes. React Native supports incremental adoption. You can add React Native screens to existing native iOS or Android apps. Meta and Shopify both used this approach for gradual migration.

Q: What is the New Architecture?

A: The New Architecture (Fabric renderer, JSI bridge, TurboModules) replaces React Native's old async bridge with a modern C++ core. It enables direct JavaScript-native communication, faster rendering, and better performance. It became the default in React Native 0.76 (September 2025).

Q: Do React Native developers earn good salaries?

A: Yes. According to industry salary surveys, senior React Native developers in the U.S. average $120,000+ annually (Nucamp, 2025). The broader React ecosystem accounts for 500,000-600,000 React-related job openings in 2025-2026.

Q: Is React Native good for startups?

A: Excellent choice for most startups. Faster development (40-60% time savings), lower costs (30-40% reduction), and ability to share code across platforms enable rapid iteration and market testing. Many successful startups (Discord, Coinbase) used React Native.

Q: What about app store approval?

A: React Native apps submit to Apple App Store and Google Play Store like any native app. They must follow platform guidelines. Advantage: over-the-air JavaScript updates don't require resubmission for many changes (native code changes still do).

Q: Can React Native handle animations smoothly?

A: Yes, with the right approach. Use Reanimated library for 60 FPS animations that run on the UI thread. Avoid animating via JavaScript thread for performance-critical animations.

Q: What about app security?

A: React Native apps have similar security considerations to native apps. Use HTTPS, secure storage for sensitive data, implement proper authentication, and keep dependencies updated. The New Architecture's strong typing reduces certain bug classes.

Q: Will React Native continue to be supported?

A: Yes. Meta donated React Native to the React Foundation (Linux Foundation) in October 2025, ensuring long-term governance. Microsoft, Expo, and major companies continue investing. React Native 1.0 is approaching after 10 years of development.

Q: How does React Native compare to Flutter?

A: Both are excellent cross-platform frameworks. React Native advantages: JavaScript ecosystem, larger developer pool (62.3% know JS), native component rendering, strong multi-company backing. Flutter advantages: consistent UI rendering, fast animations. 94% of companies using cross-platform choose React Native (Nucamp, 2025).

Q: Can React Native apps work offline?

A: Yes. Use AsyncStorage, SQLite, or Realm for local data persistence. Implement proper offline-first architecture with sync when online. Many React Native apps provide full offline functionality.

Q: What IDE should I use for React Native?

A: VS Code is most popular with excellent React Native extensions. WebStorm, Atom, and Sublime Text also work well. Android Studio and Xcode are required for building but not for daily coding.

Q: How long does it take to learn React Native?

A: For developers who know React: 1-2 weeks to become productive. For JavaScript developers new to React: 4-6 weeks. For developers new to JavaScript: 2-3 months. The learning curve is much faster than learning two separate native platforms.

Q: Does React Native support TypeScript?

A: Yes, fully. TypeScript is now the recommended approach for new React Native projects. It provides better IDE support, catches errors at compile time, and makes codebases more maintainable.
