reassure VS virtual

In this article, I presented a few simple examples of things that can cause performance problems in the long run. As you've noticed, minor refactoring led to a 93.1% performance improvement. Even though performance issues presented in the article can be caught during a thorough PR review, that can become inherently harder in complex codebases and as your React Native app grows. Making Reassure part of your test suite to address potential performance regressions and automate things in CI would greatly benefit you in the long run. Also, if you already write tests with react-native-testing-library (If you don't, you definitely should), creating Reassure perf tests is, to some degree, a copy-paste of existing tests with slight modification so that it can be quickly introduced into the development workflow. Due to the open-source nature of Reassure, if you have improvement suggestions, feel free to create issues in the repo, and Reassure team will address them.

Another solution could be virtualization (but perhaps that’s what you meant by lazy loading). Here’s a great lib for that: https://github.com/TanStack/virtual

Interesting question, although I don't know the definitive way it is handled nowadays. I think looking into the source code of the popular infinite-scroll packages might help like: react-window: https://github.com/bvaughn/react-window virtual: https://github.com/tanstack/virtual
