Project Setup
Set up your development environment to start building React Native apps.
Learning Goals
The Core Concept
There are two main ways to create a React Native app: using Expo or the React Native CLI. Expo is highly recommended for beginners because it provides a smooth, fast development experience without needing to install Android Studio or Xcode immediately. You can run your app directly on your physical device using the Expo Go app.
