🛠️ Challenge and Solution in React Native 🛠️

Hi LinkedIn folks! 👋

I would like to share a recent experience facing an intriguing challenge in React Native and how we managed to overcome it.

💡 The Problem:

Our React Native app was experiencing a notable performance issue on more complex screens. The response time was lower than expected, affecting the user experience.

🧐 Investigation:

After some analysis, we discovered that excessive component rendering was causing bottlenecks. Unnecessary components were being rendered even when they were not visible.

✨ The Solution:

We implemented a rendering optimization technique using React Memoization. This allowed us to avoid unnecessary rendering and significantly improve performance.

import React, { useMemo } from 'react'; const MyComponent = ({ data }) => { // Using useMemo to memorize the component const optimizedComponent = useMemo(() => ( {/* Your component here */} ), [date]); // Dependencies that, when changed, trigger re-rendering return optimizedComponent; }; 

🚀 Result:

Implementing this solution resulted in a more agile application response, providing a smoother experience for users, especially on more complex screens.

🌐 Lessons Learned:

Optimizing the rendering process is critical to ensuring optimal performance in React Native applications. This experience reminded us of the importance of carefully considering how and when components are rendered.
