Best Practices
When to Use:
✓ Returning multiple elements
✓ Avoiding layout-breaking wrappers
✓ Table rows with multiple cells
✓ Definition lists
Syntax Choice:
✓ Use <></> for simple cases
✓ Use <Fragment> when you need keys
✓ Import Fragment explicitly when needed
✓ Be consistent in your codebase
Avoid:
✗ Keys on short syntax (won't work)
✗ Attributes on short syntax
✗ Unnecessary wrapper divs
✗ Over-nesting fragments
Conclusion
Fragments provide a clean way to group elements without adding extra DOM nodes. Use the short syntax for simple grouping and the full Fragment syntax when you need keys. They're especially useful for table rows, definition lists, and avoiding layout-breaking wrapper elements.
