React Programming Tutorials, Guides & Best Practices

Regular profiling helps in maintaining optimal performance as the application evolves.([Content That Scales][5])

Optimizing rendering performance in React involves a combination of memoization techniques and efficient state management. By leveraging React.memo, useCallback, useMemo, and adhering to best practices with the Context API, developers can minimize unnecessary re-renders, leading to more responsive and efficient applications.

Here, useCallback prevents the increment function from being recreated on every render, which in turn prevents the ChildComponent from unnecessary re-renders.

The useEffect hook is used for side effects in functional components. However, it can lead to performance issues if not optimized correctly.
