Why Your React Native Components Re-Render (And How to Fix It)
Github : https://github.com/jmejiamu/rn-perfor...
Is your React Native app re-rendering more than it should?
In this video, I break down one of the most common performance issues in React Native: unnecessary re-renders. You’ll learn why components re-render, how React actually decides to update the UI, and how to fix it using React.memo, useCallback, and better prop patterns.
We’ll go through:
A bad example where everything re-renders
Why it happens (parent → child re-renders)
How to fix it with React.memo
When memoization works (and when it doesn’t)
Common mistakes that still cause re-renders
This is part of my React Native Performance Mastery series, where I share practical techniques to build faster and more efficient mobile apps.
If you're preparing for interviews or building real-world apps, understanding re-renders is essential.
