React Performance Optimization Cheatsheet: Hooks, Memoization, and Lazy Loading

Cheatsheet August 20, 2024
javascript

import React, { useEffect } from 'react';

function EffectComponent({ userId }) {
  useEffect(() => {
    const fetchUserData = async () => {
      const response = await fetch(`/api/user/${userId}`);
      const data = await response.json();
      console.log(data);
    };

    fetchUserData();

    return () => {
      console.log('Cleanup code');
    };
  }, [userId]);

  return <div>User ID: {userId}</div>;
}

Memoization is a technique used to optimize performance by caching the results of expensive function calls and reusing the cached result when the same inputs occur again.
