Many performance issues start (and stay hidden) at the JavaScript layer—until they impact user experience and retention.
If you missed it, we recently published the recording of Master JavaScript Performance in React Native (Part 1), where Mike Grabowski and Szymon Chmal walk through lessons you can apply immediately:
🔍 How to use the right tools to identify true JavaScript and React bottlenecks 🔍 Why incorrect usage of Context API leads to unnecessary re-renders, and how to fix it with smart memoization 🔍 How synchronous work can block the JS thread, and how to avoid it
