Callstack

In April 2023, we enjoyed talking about performance optimization in the US. We went to San Francisco, Los Angeles and Detroit to meet some amazing folks from the React Native community - we loved the intense thought exchange there!

Check out The Ultimate Guide to React Native Optimization

During these meetings, we talked about our Ultimate Guide to React Native Optimization, presented some news from React Native realm, and held Q&A sessions. We tried hard to answer all the questions, but there was only so much time, so some were left unanswered. Today we’ll be sharing these questions and answers with all of you, enjoy!

If you’re hungry for more, or you need help with performance, reach out to us. As a team of experts, we can support you with all things React Native.
