Optimize React Components Development Tutorials, Guides & Insights

import React, { useState, useMemo } from 'react';

function ExpensiveComponent({ data }) {
  const processedData = useMemo(() => {
    // Expensive computation
    return data.map(item => /* processing */ item);
  }, [data]);

  return <div>{/* render processedData */}</div>;
}

This approach ensures that the expensive computation runs only when data changes, improving performance.
