• Props & Callbacks: Passing handlers like pickedNumberHandler, gameOverHandle
• Custom Components: PrimaryButton with Pressable + pressed state, Guess list item
• Styling: StyleSheet, shadows, elevation, LinearGradient, ImageBackground
• User Input & Validation: TextInput with number-pad, Alert for invalid input
• Lists: FlatList for guess history in GameOverScreen
• Side Effects: useEffect for initial random guess

Tech Stack

• React Native
• Expo (expo-linear-gradient)
• Pure JavaScript (no external state libraries)
