React Hooks Crash Course (useMemo, useCallback and more). (Дата оригинальной публикации: )

Check out my courses to become a PRO 🔥 Starting with useState, we explore how to leverage this hook to manage state within functional components. Discover how useState simplifies state management by providing a concise syntax and powerful capabilities, enabling you to create dynamic and interactive user interfaces. Moving on, we dive into useEffect and useLayoutEffect, two essential hooks for handling side effects in React. Understand the crucial differences between these hooks and gain insights into when to use each one effectively. Learn how to incorporate asynchronous actions, data fetching, and other side effects seamlessly into your components. Next, we explore useMemo, a powerful optimization hook that allows you to memoize expensive calculations and prevent unnecessary re-renders. Unlock the potential to enhance the performance of your applications by intelligently caching computed values and minimizing redundant computations. We then shift our focus to useTransition, a relatively new addition to the React hooks family. Explore how useTransition empowers you to create smooth and seamless user experiences by adding asynchronous transitions and suspense to your application flow. Unleash the power of concurrent rendering and watch your UI come to life. Continuing our journey, we unravel the benefits of useCallback, a hook that optimizes function references, preventing unnecessary re-renders. Discover how to optimize performance by memoizing callback functions, ensuring they remain consistent across renders while avoiding unnecessary recreations. 🎁Support me on Patreon for exclusive episodes, discord and more! 🛴 Follow me on: Twitch: Twitter: Instagram: Github: #programming
