π Boosting React Performance with Memoization and React.memo
Tired of watching your React app crawl? π’ Let's talk performance optimization!
Memoization is a powerful technique for caching the results of expensive function calls. In React, we can use React.memo to memoize components and prevent unnecessary re-renders.
Here's how it works:
- React.memo: Wraps a component and only re-renders it when its props change. This is perfect for components that don't need to re-render on every state update.
-
Memoization in functions: Memoize computationally expensive functions using
useMemo
to avoid repeated calculations.
Benefits:
- Faster rendering: Reduce the number of unnecessary re-renders, resulting in a smoother user experience.
- Improved app responsiveness: Faster rendering means a more responsive app, especially on complex components.
- Reduced resource consumption: Avoid unnecessary calculations and re-renders, leading to lower CPU and memory usage.
