Unable to get it work on Expo about why-did-you-render

[vzaidman]

so the library only catches re-renders that "can be prevented" like the one I planted here:
https://snack.expo.io/HJKGvLBUH

how do you do this in this case? you move the array to the top and make the component pure:
https://snack.expo.io/Hy-YwLHUB

but the best advice is just to build apps and never prematurely optimize.

only use whyDidYouRender for HUGE components like lists and graphics which you want to make sure are not re-rendered too many times :)

BTW, any advice will be welcome ✌️

Awesome @vzaidman,
thanks for your time and clarification 🙏

@vzaidman I'm trying to use this in a component that re-renders 15x when it opens to investigate. I don't see a way to debug it with Expo – should re-render explanations be in the console.logs? It works fine when I do it with Next.js.

I don't see the logs in expo snack. Is it expected ?

I don't know what "expo" is and couldn't be able to check it out in the upcoming time as i'm in the process of moving to a new country...
