When you encounter repeated code patterns, conditional logic within loops, or similar implementations across components, extract them into reusable utilities or common styles. This improves maintainability, reduces bundle size, and makes the codebase more consistent.

Key practices:

Example:

// Instead of conditional logic in loop:
items.forEach(item => {
  if (item.type === 'special') {
    // special handling
  }
  // regular processing
});

// Extract special cases:
const specialItems = items.filter(item => item.type === 'special');
const regularItems = items.filter(item => item.type !== 'special');
specialItems.forEach(handleSpecialItem);
regularItems.forEach(handleRegularItem);

This approach makes code more readable, testable, and often results in better performance and smaller bundle sizes.
