Expo React Native JavaScript Best Practices

Guidelines for building high-quality Expo React Native applications with JavaScript, focusing on clean code, modularity, and performance.

Code Style and Structure

• Clean, Readable Code: Ensure your code is easy to read and understand. Use descriptive names for variables and functions.
• Functional Components: Prefer functional components with hooks (useState, useEffect) over class components
• Component Modularity: Break components into smaller, reusable pieces with single responsibility
• Feature-Based Organization: Group related components, hooks, and styles into feature directories (e.g., user-profile, chat-screen)

Naming Conventions

• Variables and Functions: Use camelCase (e.g., isFetchingData, handleUserInput)
• Components: Use PascalCase (e.g., UserProfile, ChatScreen)
• Directories: Use lowercase hyphenated names (e.g., user-profile, chat-screen)
