Passing new object/array/function references on every render can cause child components to re-renderโeven when nothing actually changed.
๐ง ๐๐ฒ๐๐ ๐ฝ๐ฟ๐ฎ๐ฐ๐๐ถ๐ฐ๐ฒ:
- Memoize values with "useMemo"
- Memoize functions with "useCallback"
- Use "React.memo" for pure components
Stable references = fewer unnecessary renders.

Hi @Hassan Mahmed,
Iโve just sent my application to you. Feel free to reach out if you need any additional information from me.
Thank you, and I look forward to hearing from you!
๐งช I donโt trust a mobile feature until Iโve tested the failure case.
Happy-path testing is easy.
What matters is what happens when:
โข the API returns 500
โข the user goes offline mid-action
โข a payment succeeds but the response is delayed
โข a push token expires
โข the app is reopened after 3 days
โข a deep link points to missing content
โข the same button gets tapped twice
โข background sync fails silently
Most production bugs donโt happen when everything works.
They happen when one dependency behaves differently than expected.
Thatโs why for React Native apps, I like to test recovery behavior, not just feature behavior.
A good mobile app doesnโt only work correctly.
It fails clearly, safely, and recoverably. โ๏ธ
