  • "Apply the Bootspring formatting pattern to my project"

Key Considerations#

  • Use native Intl APIs for locale-aware number and currency formatting
  • Be consistent with format patterns across the entire application
  • Handle edge cases like zero values, negatives, and very large numbers
  • Wrap formatters in reusable React components for consistent rendering
  • Memoize expensive formatting operations when rendering large lists
