Скачать или смотреть Boost React Native Performance by 50% – Best Practices

This video, we’ll show you how to optimize the performance of your React Native app using powerful React hooks like React.memo, useCallback, and useMemo.

Learn how to prevent unnecessary re-renders and improve performance in complex screens with dynamic lists and calculations.

We'll cover the following concepts:

React.memo: Prevents a component from re-rendering unless its props change. It’s especially useful for optimizing child components that receive stable props.

useCallback: Memoizes functions so they’re not recreated on every render, preventing unnecessary re-renders. Great for functions passed as props.

useMemo: Memoizes the results of expensive calculations, ensuring they’re only recalculated when the data changes, saving processing power during re-renders.

We’ll walk you through real-world examples, including optimizing swipe actions in a shopping cart and memoizing expensive calculations to reduce processing time.
