1. Overlooking Component Design

❌ Mistake

Creating large, complex components instead of breaking them down.

✅ Solution

Embrace component modularity. Split your UI into reusable, smaller components.

2. Misusing State and Props

❌ Mistake

Confusing state and props or mutating them directly.

✅ Solution

Remember, props are read-only and state is local or encapsulated. Use setState for state updates.

3. Neglecting Component Keys in Lists

❌ Mistake

Not using unique keys for list items.

✅ Solution

Always provide a unique key prop to each list item for efficient re-rendering.

4. Poor File Structure

❌ Mistake

Cluttering a project with disorganized files and folders.

✅ Solution

Organize your project by functionality and component, making navigation and maintenance easier.

5. Over-reliance on Third-Party Libraries

❌ Mistake

Relying heavily on libraries for simple tasks.

✅ Solution

Before adding a library, assess if it's necessary or if native React can accomplish the task.

6. Ignoring Performance Optimization

❌ Mistake

Overlooking performance issues like unnecessary re-renders.

✅ Solution

Use optimization techniques like React.memo, useCallback, and useMemo to prevent unnecessary re-renders.

7. Inefficient State Management

❌ Mistake

Lifting state up unnecessarily or mismanaging global state.

✅ Solution

Manage local state within components when possible. For global state, consider contexts or state management libraries if needed.

8. Skipping PropTypes Validation

❌ Mistake

Not using PropTypes to validate props.

✅ Solution

Use PropTypes to ensure your components receive the correct type of props.

9. Not Writing Tests

❌ Mistake

Ignoring the importance of testing components.

✅ Solution

Regularly write tests using tools like Jest and React Testing Library to catch issues early.

10. Missing Out on Latest Features

❌ Mistake

Sticking to outdated patterns and not keeping up with new React features.

✅ Solution

Stay updated with the latest React features and best practices through documentation and community engagement.
