React Native for Dummies 2026 – Full Beginner Crash Course
Beto, October 24, 2025 · 118,645 views
Copy-pasting AI code without understanding it is how you get stuck. In this crash course I start from absolute zero, no complex setup, and explain in plain English how React Native actually works: why Meta created it, how JavaScript talks to native code, and why Expo is the framework the React Native team recommends.
You'll build a simple Pokedex app along the way, learning the skills every mobile dev needs.
What's inside
- How one JavaScript codebase becomes real iOS and Android apps
- What the JSI bridge does and why it enables hot refresh and OTA updates
- What React Native gives you out of the box (and what it doesn't)
- Why Expo handles the boring stuff so you can just build
- Preview your app instantly on your phone with Expo Go and a QR code
- Build a Pokedex app with data fetching, lists, state, and styling
