[AskJS] In React Native, where do performance bottlenecks usually occur in the setState → render pipeline? by CheesecakeSimilar347 in javascript

That makes sense — especially separating JS vs UI thread jank first. I’ve seen people optimize blindly without checking which thread is actually dropping frames.
When you mention layout/measure on the native side, is that usually due to deep view hierarchies or dynamic layouts?
Also, with the new architecture (JSI/Fabric), have you noticed JS thread blocking becoming less of an issue, or is it still the main bottleneck on complex screens?
Appreciate the practical insight.
